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

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.
