Strizbiz ,

would be useful 4 me if it had core midi

Playing around for a minute and making droning sounds and noises is fun for a little while, but to be useful for my workflow I need core midi support, to play sound from an external midi controller as well as syncing LFO’s to other apps and drum machines, kinda feel a little like a toy right now, and it would have been nice to have more than one preset. Making it an Audio unit would have given it a lot more value. Ill keep am eye on this and hopefully it gets more added , in the meantime Ill stick to Model15

Listen to your users!!

Basically same things people have been saying for years.....its in dire need of an update and not even gonna take the time to list everything this app needs to actually BE MORE than just a noise maker and simple 4 step sequencer, because everyone else has already stated all of that..... you really should listen to your users.
Honestly would've requested a refund, but I'm stupid and had faith that the dev would actually read the reviews and take care of all that........2 stars til then
Oh and stop telling people to email you......because you apparently don’t respond or read those either lol

S-modular is cool but just a toy.

This app is cool but in order for it to be an asset in any setup it needs Core Midi support! It also would be nice if it had more modules and more I/O jacks. I hope there will be an update soon giving us at least Midi that would be great.
