Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Could it be that you're 'filtering' with the Init preset?
(I'm not on beta for this but that would be my first obvious thing to test).
Nah, I can’t find any either. If you select Init it will keep giving you a blank canvas. Although if you choose Granular and load a file you will find a lot of audio presets there.
Lots of wave presets in oscillators!
Same here too. I don't seem to be able to access Discord at the moment so reporting it here
The Factory presets are still in development. It wasn't possible to provide a Factory library when the list of bundled wavetables and samples was still being figured out (not to mention fundamental changes to the way the Mod Matrix functions).
If we had spent time building factory presets in an earlier build they would all be broken by now.
My advice is to create a new category/folder in the User area and start creating some presets of your own.
Feel free to share patches here for others to play with (you can share them from the iOS Files app > On my iPad > Buttersynth)
Isn't the presets system broken anyway? I can't even open my own, the app crashes every time I try?
This is crazy good.
Presets are indeed a little tricky,sometimes I can’t reload them but these two attached work. Also the ones I’ve created in the AUv3 version won’t show up in Files or in standalone, thus I can’t change them.
If the presets were created in an earlier build that may explain why they no longer load.
As I said, there can be no guarantee of presets working between beta builds when there are structural changes happening to the underlying mod matrix system.
Presets created in the latest build should save, reload and be shareable with no problems, however.
Actually,I couldn't reload my own preset on the same version, without have upgraded in between. Of course incompatibilities between versions make perfect sense 😊
If you create a preset that doesn’t load con the same version, make sure to report the issue to kirnu and provide him with the presets that won’t load
Makes sense. I created a preset earlier and it is loading just fine so far. If something changes I’ll report it here. I must say this synth is truly awesome!
Cool, I’m going to do this right now, I think it’s linked to FM
Agreed! There are a lot of options for sound sculpting for everything. Had a couple of crashes but it’s fun to mess with. I like the interface a lot.
I am a preset guy 😅
You might have overlooked the Curve Envelopes. You can add as many segments as you want and you can adjust the curvature between their segments. There are standard ADSRs by default but the Curve Envelopes are there if you want them.
I love curve envelopes, and having them in the synth itself means I don't have to fiddle with Flux Pro, lol. (Although that's a great app too, no lie.)
That's too much
Thanks a lot 
So now that there's no NDA...
Can we also create our own wave-tables from scratch? (Drawing waveforms has been mentioned).
And can the 'playback order' of the frames be 'sequenced'? (within the wave-table oscillator).
(I'm loving the WaveTable oscillator in Drambo with all it's shaping options).
Looking at the 'Curve Envelope' in the picture above. Do we also get 'Y-Axis Snap' options?
Being a 'chip tune addict' can the X-Grid division for the curve envelope be set in ms?(5-20ms per x-grid-line would be enough).
No doubt this will be one heck of a synth when it's released...
Can’t get over the sound…it’s phenomenal
@Kirnu can translucent overlays be made opaque as an option? At least for me seeing the instrument controls behind the menus (presets etc) doesn’t add value, yet is a more cluttered visual experience
yes there is pretty nice wavetable editor where you can draw wavetable + modify it extensively with various shaping functions controlled by sliders..
you can modulate wevetable position knob, and considering fact there is step sequencer as one of mod sources then yes, you have totally under control order of playback..
nope but this is good idea for future improvements, will add it to feature requests list
Thanks, think of the y-axis grid-snaps as 'destination values' (12 semitones, X wave-table index entries etc.).
With snaps the values change instantly (chip arpeggios with semitone snaps) while using curve the values 'glide' (ie. crossfade between wave frames). With x & y snaps the curved envelopes become step-sequencers on roids
Setting the 'x-grid' duration in ms in addition to beat divisions would be a nice bonus
I have a feeling Butter is worth waiting for so no need to rush...
3 instances of Butter Synth, no external FXs ... (just trying to feed the hype a little bit 👹)
arpeggio is made using build in BS arpeggiator (which is pretty amazing)
This
IS
FREAKING
WONDERFULLLLLLLL!

Very nice!
So what's the 'magic touch' to interpolate one wave to another when creating a wave-table?
And can I use 5 sample-layers if I want to?
I would swap places of 'Init' and 'Cancel' when initing a preset...
...motor memory is important and most other apps have it that way
