ButterSynth

I love the sounds. I hadn’t used this instrument in a while, started playing with it tonight and as I scroll through the presets, I’m finding that some are already sounding without me touching any keys. If I scroll past that patch, the next presets are also sounding, have to shut off all MIDI notes to get it to stop.

Amazing workflow and sound. 10 stars!

This is an absolute definite hall of famer in the upcoming Renaissance, My sincere apologies for not being able to write down the details but it’s coming. Two options 1) buy it 2) ignore option 1 and buy it now

Limited selection of wave tables. Most are just single samples. Sample module has consistent buzz with unison and all effects/modulators off, whereas same sample in Koala with no effects sounds rich and full. Not sure what your signal path is like but I can’t get a reasonable sound. FM module is very limited. LFOs are extremely simple to the point uselessness. Like, seriously, no phase offset? Just amplitude and rate? I mean how’d you lose one of the three complete waveform descriptors? Terrible.

I’ve successfully recreated synths from popular songs with this app alone for a much lesser price. It would help a lot to make additional midi mappings such as a toggle for the arpeggiator. I’m fairly new to this app so this feature may or may not exist… yet.

I love the character of sound this app provides but I have a few requests for possible updates. 1) The square wave LFO is not square. It sounds like it’s running through a slew limiter. You can’t use it to tune interval jumps without glide. It always has glide. No trills possible. 2) Same for the step sequencer. It always has glide/slew. No discrete steps without glide. The modulation matrix is what sold me on the app but these basic routings offering unexpected results makes me wonder what else I might run into. The waveform system is absolutely wonderful and the filters sound great. Hopefully slew (and sustain pedal) can be addressed in updates.

Amazing synth, fun to use, but I can’t save my preset. Save button just doesn’t do anything… gonna have to use SynthMaster, I guess. Also, there’s no undo function in the wave table editor, which is very unfortunate.

In Cubasis, AUM, or Audio Evolution. Does show up as IAA, and standalone, if this bug is not fixed I want a refund. If it is fixed quickly I will amend this review, but currently one star as it is useless to me.

Every single time I press play it changes to another preset. I just bought this. I’m very disappointed. I thought it would be better.

I would pay a hundred bucks for this as a VST. I’d use it over most synths. It has everything, and I really like the filters… which isn’t super common among synths that lean heavy into the digital stuff. I can’t get over the fact that it literally has everything I would want including real 4-op FM synthesis (the fact that you can build a custom library of waves to FM with is amazing). It could only be better if it included phase distortion also. The interface is great, it reminds me of when synths were deep but upfront about how it’s all presented. A lot of synths have gotten away from that trading it in for stylish looks. I’m not saying this synth doesn’t look good it does, but it seems to remember a more straightforward way of doing things. It’s a real masterpiece. Don’t even get me started on all the tools provided here, it really contends with the best iOS or otherwise.
