## ButterSynth Description
ButterSynth is a hybrid 6-oscillator wavetable/FM/sample-based AUV3 and standalone synthesizer with a vast sonic range, from gentle pads to screaming leads and basslines. 
Mix any combination of wavetable, FM, sample and other synthesis engines for one truly massive sound. 
For the more advanced users, you'll love using ButterSynth's thoughtfully designed interface, incredibly powerful modulation matrix, fully-featured internal FX rack, factory waveform and sample libraries, and almost limitless scope for fun, experimentation and sound design. 
For less experienced synth programmers, ButterSynth includes a library of hundreds of ready-to-use presets, sparking your creativity to start making music right away.


Headline features include
- Mix and match any combination of 6 synthesis engines to either emulate your favourite synths of yester-year or build a synth ready for the future. 

- Dual-wavetable engines also feature 9 phase modes, wave folding, and deep unison controls modelled on vintage hardware synths. 

- Built-in wavetable editor gives you the ability to tweak, morph, and hand-draw your own custom wavetables, with each wavetable supporting up to 256 frames. 

- FM engine offers 4 operators with a selection of 12 modulation paths. Each operator can be loaded with any waveform from the factory or user library, and can also self-modulate via the feedback dial. 

- Sample and Granulator engines both let you load samples (either imported or from the factory library) and control precisely how they are chopped, triggered and layered. Both also feature the same powerful unison modes available in the WT engine. 

- Highly configurable 32-slot modulation matrix featuring precise mix/max ranges, self-modulation (via the amount target), plus configurable response curves and layer modes. Simply long-tap any parameter to set it as a Mod destination! 

- Full suite of versatile control sources which includes: 4x MSEG-style looping curve envelopes, 4x LFOs, 4x step sequencers, X/Y pad with motion recording, 8x Macro dials and a powerful arpeggiator inspired by Kirnu Interactive’s Cream. 

- The EFX rack lets you build your own insert effects chain using any combination of the 16 built-in FX modules. Modules available at launch include delay, reverb, distortion, chorus, OTT compression etc. Note  - FX parameters can also be targeted by the mod matrix, unlocking the possibility to program ‘per voice’ modulated effects. 

- All presets, wavetables, samples and other settings are stored in the Files app, making bulk import/export, backup and community sharing quick and easy. 

- All of this is housed in an irresistibly designed 4-tab UI that makes synth programming quick and fun.

## ButterSynth Reviews in United States

### **--- "Changing a patch spikes my m4 to 99 percent"
Changing a patch spikes my m4 to 99 percent.   No way to contact the developer on their website.
-- Valuedcustomer8, 2025-05-03

### *---- "Everytime i render the track or freeze it Theres no audio"
this synth is good but it keeps crashing and bugging out and when I try to freeze or render it to audio it either crash or doesn’t show the audio or it will have like a little bit of the sound and the rest is gone in a bad way. Please fix this bc I use the sample for 808 and it’s good for sound design. Please fix this

Update: it keeps crashing and it’s Annoying theres not even a buffer size  on the synth please fix this please. I like using this synth for samples

### ***** "Deep Surprises"
ButterSynth allows you to program from several different ideas. It is a deep, great sounding synth that can be a sounding as you like or weird and exotic.
This is why I am so fond of this synthesizer. When programming there are many approaches that can be same sounding, but typically offer timbres that are somewhat similar and yet very different sounding until you realize the base of the sound starts from similar areas in the synth well producing different concepts taken from the same beginning.
Personally, I’m not a big fan of the interface. It’s set up in a way that wastes a lot of screen space. And don’t necessarily come from the same style, which can be a little bit disconcerting and for me at least takes a little bit more time for me to figure out where I wanna go next. However, where I wanna go often ends up someplace different and interesting so in that respect as a user you end up in different places, different representations, and places you didn’t expect to find interesting but are. For that reason, I love this synth and find myself using it way more than I expect. Because of this, it does have a learning curve. I do hope that they approach the graphical user interface because I think that underneath this particular UI there is something exceptional waiting to occur. But if it never changes, there’s so much you can do with ButterSynth and I find myself drawn to its sound no matter that sometimes I spend more time than I would like trying to navigate features. The unexpected sometimes yields results I would personally never think of and that’s great..

### *---- "unusable"
Keyboard doesn’t load on iPhone.
-- Nkains, 2025-01-20

### ***-- "Great sounds, but some patches hanging"
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.
-- jpdenk, 2024-10-16

### ***** "Can’t believe it is butter lol"
Amazing workflow and sound. 10 stars!
-- sweatshop beats, 2024-08-30

### ***** "Haven’t explored completely but……"
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
-- Deathrow Inmates, 2024-08-14

### *---- "Not very good"
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.
-- PDXPNWORWA, 2024-05-31

### ***** "Almost top tier, yet deserves 5/5"
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.
-- Akf220, 2024-05-03

### ****- "Great with hopeful potential"
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.
