ButterSynth

First of all, great Synth! 😊 I need your help, i am not able to access to piano roll on my IPhone 15… No problem on Ipad installation but no way on IPhone… Sure i am doing something wrong but I do not know how to achieve it… Thank you!

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.

I love the power and sound of this synth, and I find it much more usable than both the synthmasters, which I could never warm up to. It’s mostly intuitive, and the developer is clearly committed to the product and listening to users in forums. However, a few things are odd to me: 1. There’s no button for filter key follow! At least 1/2 and full are pretty standard. Yes, you can set it up in the matrix, but it’s something that should have a button like every other synth, and there’s room for it in the ui. 2. The curve of the envelopes is odd, with the release especially being weird. It ends pretty abruptly, which I’ve never heard any other synth do. Again, there are other envelop options, but I don’t want to use the curve envelope for something simple if I don’t have to. 3. I get crashes with one instance in AUM using the unison function on an m1 iPad Pro. Seems like a bug? It created crazy full-volume white noise that hurt my bands ears when it crashed too. 4. I find the matrix extremely fiddly with the min and max knobs. I wish there was an easy way to only have amount to speed things up.

There is a keyboard you probably hid it ya doof. Don’t handle heavy machinery please
