Hello, everyone! I released CS-16 last year in July (man, time flies!) but I never made a forum post. So, here we are!
CS-16 is a simple 16 track synthesizer. It has an up to 128 step sequencer (but this may change 
), a sampler, sample editor, and has many customization options.
Here's the introduction video, and a couple screenshots:
And once again, it's free and open source on GitHub. Have fun! 
Hello, again!! I'm very excited to announce CS-16 version 2.0!
In this update, I added the fourth and (probably) final screen to CS-16: FX! Here you can add effects to the master audio channel. Currently there are four effects: TAPE (low pass + high pass), BTC (bitcrush), WTR (low pass), and OVD (overdrive).
I also added external visualizer support, custom track names, and fixed a lot (and I mean A LOT) of bugs.
Download the latest version here!! Hope you like it 
I love the font! Did you make it yourself?
Nope, it's the Tron font from this repository, modified to add punctuation and the like 
I just released version 2.0.2! Just a bunch of tiny fixes and improvements, nothing major
[added] folder precedence over songs / files in file explorer setting
[fixed] settings screen 50fps warning
[fixed] ramona custom visualizer in light mode
[moved] .wav file save setting is now in sampling/
I just released a small bugfix update (version 2.0.3)! Please check it out if you have any issues with the list views in CS-16.
(Sidenote: SDK 2.6.0 introduced this bug, even though it was lurking in my own code probably since the beginning of its development 
)
Version 2.0.4 is now out!! Song tempos can now be any BPM between 15 and 480 (yes, even your weird tempo of 134.8), listviews now perform better on device, and two new external visualizers have been added, dithered notes and cpu stats!
