User reviews

great tone workshop

Amazing reverb, have had the app for 7years and learned overtime much about the morphological beauty of granular synthesis. Certainly not ABSOLUTELY perfect, but 95% of it is. The most notable thing is the reverb disengages upon a notification or phonecall, but to get it back engaged, one simply moves the “gain” or “wet” reverb parameters a wee-slight bit, then the reverb is fully present most importantly, the way you had it set originally. The one issue I wish wooji juice to buckle down is the “arppegiator” tempo really isn’t fully accurate, and it seems only explained by comparing how powerful the synth and signal path can be that maybe there isn’t enough left in the App to ensure real time BPMs. I love the idea of the parametric sequencer but it’s under the same clock issue so i don’t use it because it can’t articulate smooth parametric changes if the clock isn’t on time. One of the many home runs is the “lock” for the keys, and the “chord” arppegiation which can be used to compose MASSIVE drones and soundscape, morphing guitar sweeps(if you record into the mic) and sequences that take about a month to cycle through. Combining that with the most notable tool, the parameter LFOs found on about 90% of controls(including flange and chorus rate for doppleresque effect!) you can modulate both octave and pitch with their own respective wave shapes and make sequences last over a year, see you next thanksgiving! The xy section is a truly advanced area and should come way after one grasps the apps main functions, along with the ribbon controler. One more occasional glitch occurring during looping grains can be heard to shift harmonics for no reason, so just switch out of the synth mode during looping and switch right back, glitch erased. so these two glitches can be worked around, i would ask apple to implement a sixth star if you make the clock keep accurate BPMs, but pretty sure your over it. I’ll still enjoy the inter dimensional sounds coming out of this phone, regardless. thank you.

Won't Open Anymore

App will not open. Crashed instantly.

Really wish it had AUv3 support

The engine sounds really terrific, the UI is intuitive, and the app supports multichannel midi input. It doesn't yet work with Audiobus 3's MIDI input feature, though, or support being loaded as an AUv3

Classic must-have granular synth

Some fantastic sounds. Highly recommended. Thanks for the update, Wooji Juice!

A winner

I think I may love this synth even more than the mighty Mitosynth.
