Concerto
By kliepatsch
This is an old video (hopefully I'll be able to make a new one soon):
The CONCERTO synthesizer is what I intend to be the sound generating side of a music making software for the Commander X16. It uses the 16 voices of the VERA and the 8 voices of the YM2151 and aims to get the very maximum out of them. It is not quite there yet but has a lot of strengths already. The main features:
32 synth timbres (i.e. sounds) 16 monophonic channels, each playing a dynamically assigned synth timbre up to 4 PSG oscillators and 1 YM2151 voice per timbre up to 3 envelopes and 1 LFO per timbre pitch, volume and pulse width modulation vibrato volume control per voice ("velocity") pitchbend save and load presets / banks (a bank is the entirety of all 32 loaded timbres) comes with one bank of "factory" sounds Features that are planned (for the sound engine):
volume and vibrato automation If you have problems with the audio quality in the "Try it now", download and run in the offline emulator with the command line option "-abufs 12" or more.
To use file loading and saving, you must use an SD card.
For more information, look into the README and the source files and/or send me a PM.
If you find bugs, please let me know, or post an issue on GitHub.

PSG Piano
By SlithyMatt
This is simply a single-octave piano that lets you select up to 4 waveforms to play simultaneously at the same frequency, at any chromatic note in the octave starting at Middle C.
All controls are illustrated on the screen, with the number keys acting as toggles. Waveforms highlighted red will be played at full volume for any note.
Code is available in the Lesson13 subdirectory of this GitHub repo: https://github.com/SlithyMatt/x16-assembly-tutorial
You can see a demo of this program (along with a lesson on how use the VERA PSG with assembly language) on YouTube:
If you are a member of my Patreon community (https://www.patreon.com/slithymatt) , you'll also have exclusive access to a video in which I give a complete code walkthrough for this Piano program.

Command Tracker Pre-Alpha
By m00dawg
I've since removed the external file dependencies for building the UI which means folks can finally try Command Tracker out more directly in the emulator. A very basic song exists to start. There is no loading and saving yet and, as noted in the dev log on the forums, it's buggy and, as of yet, no real sound engine (rather a very very basic one) but it does work and demonstrates what I'm trying to work towards in a full featured tracker. It is modeled loosely after Impulse Tracker on PC.

Music Player Library for BASIC Programs
By DusanStrakl
I wrote a library to enable BASIC programs play music in the background.
It is compatible with Simplest Effects Sound library I released a while ago.
To demo the library I included two BASIC programs:
PLAY.BAS - Playing Twinkle Twinkle Little Star - it demonstrates the BASIC program doing other stuff including calling simple Effects
HOUSE.BAS - Playing House of the Rising Sun - it demonstrates a bit more complex music
Full Tutorial and source code is available from my blog:

Tiny PCM Synth
By kliepatsch
I wanted to explore the possibilities with the PCM output. This tiny synth generates a sweet tone from three sine waves, coated in a thin shiny silver layer of aliasing. To spice it up, I also added a delay effect. You can play it with your keyboard. Use Z and X to switch octaves.
I do not plan to follow this route any further, because the possibilities are quite limited with the X16. I am sure one could do better than I did, but the X16 doesn't have enough power to provide a whole lot of flexibility in the sound generation (at least with PCM).

Feel free to reuse the code for your own projects!
