This is a nice little app, but very barebones. Really needs some more controls, and load/export functions and all that. I assume it was just a short small project for you, and you have move on long ago and abandoned it?
I'm somewhat interested in writing a similar sequencer/sample looper app, because I noticed that almost all available tools for PC are either abandoned and the better ones are locked behind expensive subscription paywalls (well, their target audience are professional musicians after all...)
So I'd like to ask where you got the sample bank you're using from, and if it's still "free" to get and use.
