- Can you add a decay slider to each channel? That shouldn't be hard. It could change the sound & balance of the set by a lot.
- Also panning is very useful..
- The repeat every n bars is a very nice touch. Trig conditions are out of the question i guess.
- A random button would be lots of fun and make users stick around more. It could have a percentage parameter, too. Could be used as a starting template each time you reload or revisit the page.
- The sliders could be a bit wider, especially the one for tempo.
Not too detailed though.
