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

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.

Unpredictable Like Real Analog Synth

Just like a real semi-modular this app is unpredictable and sometimes hard to get a musically useful sound. However, if you like to mess around with sound design, this app is quite capable of generating some excellent soundscapes that are ideal for sampling. I agree that core midi, more presets, ableton link and more effects would be terrific. For the price, this is a nice app that provides a somewhat realistic experience of the joy and frustration of working with real analog synths.
