Music_SDP changelog:

*We deeply apologize that the changelog hasn’t been kept up-to-date. In the coming days we will be going back and providing changelog for past releases:


[Beta 1.4.0] 2018-10-06


New System Features:
Upgrades to engine –  means that everything in the program runs faster. MSDP starts up faster, boards and modules load faster, making the entire program more performant.
New Dials that allow for more accuracy, has better control, more aesthetically pleasing
Delete Board – new window allows you to remove boards from your projects
Project Save Confirmation – Quick confirmation lets you know that your project save was successful.
New Organization to Modules and new ‘Control’ category – With a wealth of modules designed just to control performance of other modules, this new category was created to clarify function.
New Modules:
Spectroview – vew signal as a spectroscope or sonogram
LFO Control – New module to allow LFO values to be mapped to parameters in other modules. Can combine up to three shapes
Score Control – new module that allows you to create and load scores. Replicates what’s possible from the System Board, but now you can load multiple scores as multiple modules
MIDI Sequencer – You can now create MIDI sequences to control instruments.
Hardware Mapper – Same functionality as Controller Setup on System board. By re-creating as module, gives more granular control of hardware and allows for multiple hardware to exist in one project.
cREepyVERB – A reverb that includes fluctuation parameters that get wild when set to extreme values…
New Module Features
Metro Sync options added to Stochastic Files, Grains, and Controller
New Developer Tools
MSDP.Builder – A new tool that streamlines module creation, this tool generates all of the UX elements needed to connect your ideas to the Music_SDP interface without having to remember the names of objects or how they connect to each other. Just select what you want to make, and the builder will generate it and hook it all up for you!
Fixes / Improvements:
  • Fixed problem where saving a project with a minimized board resulted in a board that you couldn’t see upon re-load.
  • Metronome not resetting to measure 1 is fixed
  • Metronome loop not working is fixed
  • Controller automation will start even if default start and stop times are used
  • All module inputs have default values affixed for numbers. Resolves some issues with setting I/O by only changing letter value and not number value
  • System Settings renamed to System Preferences. Board Browser (depricated) has been removed as an option.
  • Confirmation window appears on project save
  • Removed issue where line objects and dials create duplicate outputs
  • Randomator – value display doesn’t update as often. No need to share so much data, it’s updating in the target module anyway.
  • Less background flickering on/off on startup/project load

[Beta 1.3.0] 2081-07-14

Major updates for Music_SDP 1.3.0 release:

New Project Save feature includes complete save and reload state – includes all of your modules, even open ones, and all your system board settings. Pickup exactly where you left off!

Resume Last Session – pickup where you left off, even if you forgot to save!

Synths now respond properly to velocity – individual pitches may be louder or softer (higher or lower on software keyboards).

New Wavetable Synthesizer.

Revised Metronome and more than double the number of tempo sync options.

Easier-to-use module templates, a new rhythmic module template, and more dial options and tutorial templates added.

Fixed issue with MIDI modules where the destination IDs would need to be re-entered upon module reload.

Fixed the following Chaos Synth issues: First slider didn’t send out any signal, tabs didn’t save, fixed issue with only have one oscillator on. In Keyboard mode, pattern starts at the beginning when turned on.

Virtual Keyboard can now be played on your computer keyboard.

System Preferences window gives you more control over you audio settings, new project settings, and user feedback.

Simplified and improved Project Settings window.

Save Project button added to boards for quick and easy saving.

[Beta 1.1.5] 2017-05-26




Major Project Updates:

Sierra support has been implemented

An overhaul to processes behind how we build Music_SDP means that Sierra’s new security measures no longer break the functionality of our program.

Mac installer is now simpler –

No more folder structure, no more extra installs. Just open the installer and follow the one simple step to get everything you need up and running.

Java has been removed –

Thanks to a new external, Music_SDP no longer relies on Java to control project file management. Because of this, no user needs to install or maintain any version of Java in order to run Music_SDP on either Windows or MacOS. This also frees up system resources, meaning you should be able to do more in Music_SDP before running out of CPU overhead.

Source-Code includes new launch options –

For Max users who want to look at the source code, new launch options have been added, making it easier to test code and to explore patches.

GitHub has relaunched for access to experimental releases –

Source-code users may now look to our GitHub repository to find our most recent experimental releases. Keep up-to-date with all of our work as we make headway towards the next stable release, and try out new features along with us.

New Module:

Chopper 2 –

New live audio chopper with a multitude of options that allow for unexpected glitchy results. Includes Basic mode, Grid mode, and Keyboard mode.

System Updates:

Music_SDP folder now added to Documents tree –

When launching Music_SDP for the first time, either as an application or as source code, a new set of folders will be added to your Documents path. These folders allow Music_SDP to keep track of projects from a central location, and make it easy to add third party modules without having to re-install them when new releases to the application come out.

Cleaner, rewritten project loader –

The project loader now closes entirely once a project is selected, freeing up system resources. Behind the scenes, the code has been cleaned up, making it easier for explorers to navigate the inner-workings of the patch.

Install Music_SDP anywhere on Windows

Previously, MacOS users could install Music_SDP to any location on their hard drive, which Windows users were limited to installing onto the root of their C:\ drive. This is no longer the case, and Windows users can now install to any location (the default is now your “Program Files” folder).


EZ File Player no longer outputs to a mystery source –

The mystery output source has been tracked down and eliminated.

Gater no longer sends out bangs to console when activated 

This is self-explanatory.

Fixes applied to System Board –

Several small fixes and improvements have been made across the system board code.

“Unidentified Developer” issue resolved –

We are finally Apple Certified developers, and it is reflected in the installation process on MacOS. Users should no longer encounter “App is Broken” message, or the message stating the Music_SDP is from an “unidentified developer”. You’ll still be asked to confirm that you want to open an application that’s been downloaded from the internet.

New Visual Assets:

Dean Berlinerblau has created a new version of the Music_SDP logo icon that should make it easier to see on more desktops.

[Beta 1.1.4] 2017-03-12


Major Project Updates:

Open audio/MIDI/VST files from anywhere on your computer without having to add them to your project!

With the new option to search your computer for media files, you are no longer required to load media files into your project in order to use them in your project. Note that audio loaded this way will be saved with your boards, but media files will not be saved with your project. The files won’t won’t work when reloading a board if the file is moved or if the project is opened on another computer. However, for users who don’t share their projects, this is a great way to save on hard drive space and avoids creating excessive duplicate files!

This idea came at the request of an MSDP user named Pedro Martin, who got tired of re-loading the same VST files over and over again with each project he built. Once Pedro sent us the idea, it seemed like the most obvious thing we’d never thought about. Thanks for the idea Pedro!

Music_SDP is now 64-bit and we’ve updated our Java classes to work with the newest versions of Java Runtime!

OK, we understand that most of our users won’t be too excited by this news, but going 64-bit and updating our Java classes keeps us in the game as technology continues to progress. Sticking with older technology meant that eventually MSDP would have stopped working on modern systems. Keeping things technologically up-to-date makes sure that our software can continue to run in the coming years. Users will have to install a new version of Java Runtime, but it’ll be worth it, we promise!

We’ll be plastering the site with information about downloading Java Runtime 8, so don’t worry about finding it, we’ll help you out!

Music_SDP is now Apple Certified

OSX users will no longer have to jump through hoops to get Music_SDP to run on their computers. The “App is Damaged” issue is no effectively resolved. Users still need to make sure that their security settings allow them to open applications download from the internet.

Get the latest news and learn about software updates in the Project Browser!

Now, when a new version of the software is available, you’ll know as soon as you open the program. Our unobtrusive notice at the bottom of the Project Loader screen let’s you know that a new version is available to download and offers a button to open the download page in your preferred browser!

The new Recent News section of the Project Loader finally puts the right side of the screen to good use! This section will let you know about upcoming releases, the newest additions to our YouTube channel, and will even provide a look into the music that our community is making. MSDP is going online!

We have (the first part of) a User Manual!

The User Manual is a big undertaking, and detailed documentation will almost certainly take more than one update to complete. But we’ve finished the first 100 pages, and there’s plenty here to pour through and learn from. The User Manual will only be available online for the time being, so that updates can be shared as soon as they’re made. A link to the newest version of the User Manual will now accessible from the Music_SDP menu on OSX and the Help menu on Windows, and we can let you know when updates are available via the Recent News section!

New Module:

The Glitch Pad

Who doesn’t like glitchy and gnarly sounds? The new Glitch Pad lets you scrub through your audio files while turning them into glitch soup! Different audio files will make different glitchy results, and the pad can be “played” to design all sorts of beautifully nasty creations!

System Updates:

Total overhaul/revamp of the Signal-2-MIDI module
We’ve switched over to a different pitch-detection algorithm for the core of the module that works significantly better than the original. The new algorithm provides far less junk data, is more accurate, and is more CPU efficient! On top of that, there are now two primary modes: Stream, and Musical. Stream mode sends MIDI data continuously, while Musical only generates new MIDI notes when a note starts. The previous options are all still available, but can be selected in both modes!

The Automator Board finally has the modern preset system implemented
If you’d asked me a month ago why the Automator Board doesn’t have the same version of the preset system as the rest of the program, I would have looked at you with confusion… primarily because I didn’t know that was true! Admittedly, this is one of the flaws of such a large program being designed by such a small team; it can be difficult to keep track of each aspect of the program. But, as soon as the issue was brought to my attention, I jumped to fixing it! Now, Automator Boards can have preset files saved and loaded with the same ease as the rest of the program. Plus, we hugely expanded the preset bank so that you can save a massive number of automation messages with your projects! Thanks to Dean Berlinerbrau (of new MSDP logo fame), for bringing this to my attention!

Load First Score Event on Project Launch no longer requires loading saved boards
With this update, users no longer need to have a saved board load on project launch in order for the “Load First Score Event on Project Launch” option to function Properly.

Performer Instructions are now accessible via Automation
Using the automation ID “MSDP_Performer_Instructions”, users can now automatically open and close the performer instructions page, and can also replace the title and the content with new text. Parameter names are “open”, “close”, “title”, and “content.”
