This looks and sounds beautiful! Is there any way to turn off the reverb and add our own samples? Is odd-time possible? It looks like it could be.
Hey sorry for the late reply :) Yes it totally is! This is a MIDI sequencer, so you can connect any device you like to it :)
Looks pretty, but i didn’t have a chance to try it because of some bug that doesn’t allow me to change MIDI output, so i can’t output the signal out of it.
Those are some wild shortcuts :D if it doesnt work due to those you can still click on the menuitems and also on the small buttons [M] for refresh and [</>] to switch between devices. If devices cant be detected at all and a restart doesnt help either it might actually be broken sadly :/ what os do you use in that case? and to which device are you trying to connect?
Hope it all works out and thanks for messaging :)
Seems only the menu/shortcuts were broken/missing/duplicate, the buttons should still work :) but I uploaded new builds (0.1.1) that should fix the issue with the menu :)
I’ve actually tried all of them - they are changing MIDI Input only. And the new version actually fixed this, so thank you! c: It’s time to write something (maybe) awesome :D
Glad to hear, enjoy :)
