Why do I have so many synths...?
A) They don't all make the same range of sounds
B) Some synth UIs (workflows?) are simply more immediate and fun to use.
Call me shallow, but I often find myself reaching for the plugins that are more enjoyable to use and the ones that encourage me to experiment and program with them. ButterSynth puts a massive big tick in that box. It's a UI that is friendly to pros and beginner synth programmers alike.
Of course, it also helps that it's capable of such a wide array of sonic landscapes. and those FX
I’m glad to hear that! 100% true about the fun factor and inspiring UI being really important and producing different results. I have myriad synths but I’m getting this one too. I just thought that meme was funny…
Very good question… there are many things, few most important:
1/ Oversampling for oscillators, filters, overdrive
All processes where is risk of digital aliasing/nonharmonic distortion .. this costs CPU and many devs do not use it to save CPU but then it results to nasty alising noise (try put resonance to max in Model D and then sweep cutoff - you will hear nasty noise sound on high cutoff value)
Bad example where leads lack of oversampling on oscillators is Bleass Omega - example i posted above. Also Megalit is suffering by this problem - try play square wave on high octaves in Megalit - you hear nasty alising (that digital noise you hear on background of played sound - i can record example if you want).
One would say this is just example of extreme situation - but those are exactly problems, which when solved properly, have profound impact on overall “good” sound of synth.
Compromise solution for oscillators is to use bandlimited waves - basically limiting spectrum of oscillator’s wavetable with lowpass filter so oscillator doesn’t produce that much high frequency content ( which can lead to alising on higher octaves or with FM midulation or overdrive is applied) - but then oscilkators starts sounfing thin and dull.
2/ Smooth modulation - for example filter - when you do slow sweep with high resonance, you should not hear “stepping” but it should be completely smooth even for very slow sweep. Same can be applied to pitch modulation. But thus is needed to be properly handled also for FAST sweep - there you need to use smart way of interpolating values with some inertia to preserve smoothness but change value fast enough - again horrible examole is Audiokit Synth One - try do filter sweep very fast (just set resonance somewhere around 50% to hear it, then use saw oscillator, without any othwr modultions try quickly close lowpass cutoff from max to zero - you literally hesr how value is changing too slow even after you moved knob to zero value)
3/ High enough modulation rate - mod rate is frequency with which synth engine applies modulation data (envelopes, lfos, ..) to modulated target (filter, pitch, etc). Ideally it should go to audio rate range - but this is really CPU hungry so often it is uses significantly lower frequency. But then things like fast envelopes or fast LFOs doesn’t work good (for example you can’t make proper snappy percussive sounds with that synth), and it also technically limits max frequency of LFO (for example if mod control rate is 100hz, texhnically max possible frequency of LFO is 50hz but even at that freq, when you apply let’s say lfo>pitch mod, it sounds ugly - it sounds like “computer bleeps” - unpleasantly digital - not smooth like on analog synths.
There is lot more things and they are details when analysed just onnit’s own, out of context - but they all add together to overal synth sound. Of course DSP coding is always about compromises - more quality you want to achieve, more CPU it costs.
Does Buttersynth have its own soul in the sounds it can create? I understand it is a Swiss army knife, but I find that a very uninteresting feature, something that ‘does it all’. So, I am curious.. is there something in the sounds it can create that separates itself from, lets say a Moog, a Korg, a Juno.
Yup, that’s why Model D and Tal Juno are still in my collection :-) (even through weak side of Model D high resonance filter behaviour - rest sounds good)
They have very speciffic sound of oscillators and filters, which is not that easy to emulate with other synth (not impossible, but it needs lot of work, so it’s simoly easier to use directly them)
I have pre-ordered of course, and I hope the UI is as stimulating/straightforward as many here suggest, but the main reason for putting the inevitable hand in my pocket (this time) is Cream Mobile, which I never made the most of, but admire tremendously...
Besides filter design (which is no small thing), oscillator waveform. Real analog synths don’t have perfect square , ramp (saw) , triangle or pulse or sine waves. Virtual analogs get some of their character from not using mathematically perfect waveforms.
Btw, sine waves are going to generally be the least distinctive feature and filtering one will reveal less character than filtering richer waveforms.
Some synths will introduce saturation of distortion in some conditions..or have non-linear response got some things. How the keyboard tracking is implemented can vary.
On the sine wave front, Buchla easels (and maybe other Buchla’s) had/have a sine wave that is almost a triangle.
the gush on Buttersynth I get.
I havent heard mention here of what seems to me the closest comparison- Synthmaster.
I don’t hear much about Synthmaster in general these days..
I'm not qualified to endorse that statement, but it IS one of the most-pregnant-with-truly-magical-stuff-seemingly-just-beyond-my-reach apps ever
I have SynthMaster 2 and rarely use it..although, to be fair, I usually reach for my hardware synths before all else. That said, the UI and layout of Butter Synth looks far better/cleaner than SM2 to me.
Speaking for myself, due to the instability of their synths and a series of never addressed technical problems (such as stuck keys) I've pretty much given up on both of their synths (both the iOS and desktop versions) and have moved on.
Oh yeah…that too. I don’t have an issue with stuck keys but SM2 doesn’t work in Keystage at all. 😕
Among other things, wavetable editing.
Does anyone have a clue if the price will go up after pre-order period is over?
I asked that earlier in the thread. Apparently no one knows.
I'll find out...
Thanks for this. Really interesting 👍
Can anyone confirm if the latest TestFlight version is equivalent to the upcoming release version?
more or less yes.. there may be some minor bugfixes but it is considwred as release candidate
Thanks!
Indeed, thank u @dendy!
Specking about synths with unique sound, I love IVCS3. To my ears it’s beautifully imperfect and growls nicely. But man, it’s so hard to tame.
An issue with great and unique synths like IVCS3, ID700 or even modular ones like Model 15 is that they might be manageable after some adaptation time time for users versed in synthesis. But are beyond the reasonable for those of us that still struggle with synthesis concepts and flow. With synths like ButterSynth you’re limited by your knowledge of concepts, not in how those concepts are implemented.
And most imortatly way much better UI - very important point. SM2 UI is absolute mess.
I bought.
Its more exciting buying an app before launch.
Like a xmas calendar.
Kind of hope the fm isnt better than Nambu but I doubt it is.
Can you choose oscilator order or amount. Like Nambu?
All wavetable or all granular etc.
BS is much better now than 2 months ago, no crashes, ability to load folders of samples…. This is huge progres.
I like granulqr and wavetable sections a lot. Prepared small pad patch and when I repetition one 4-Voice chord (polyphony set to 16) , thesame 4 notes, sound is cut to silence.
Would be nice to be able play the same chord over and over and only oldest voices should be cut, due to polyphony limit, not new with old all together, right? Maybe this will be fixed, I hope so. What you think?
Better describe this small VIDEO:
Yeah Butter Synth has just a phenomenal UI. And indeed, SM2 UI is lacking big time. It is a pity that the Buttersynth sampler is not anywhere near as developed as it could be, that seems like the main weak point so far and is definitely puzzling in an app which otherwise shows such attention to detail.
No they are fixed, 2x WT, 1x sample, 1x FM, 1x GRANULAR
