Very Inspiring!

Great fun right from the start and as deep as you want it to be once you’ve got your head around all the possibilities. Can I make one request, though; could you make it possible for the four voices to start at different points and move at different speeds and directions, please? Then it would be perfect.

Wow OODA

I like that you can sequence up to 4 voices and time shift each individual voice.. nice interface and lots more! Does it need a scaler though?

Deep and fun!

By far my favorite sequencer. The voice panel, and the fact that it is separated from the steps is very powerful. Be sure to check out the tutorials on YouTube.

Two improvements I’d love to see:
— copy/paste of steps
— and maybe an option to see which notes have been recorded into each step

Deep and fun!

Wow! By far my favorite sequencer. The Voice panel, and the fact that it is separated from the steps is very powerful. The UI is set up thoughtfully and very easy to master.

So good, and easy to get lost for hours in it. Be sure to check out the tutorials on YouTube.

If anything, sometimes I’d love to have an option to see which notes have been recorded into each step. But maybe this would make things too convoluted, idk. The current balance between complexity and simplicity is perfect.
