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.

ButterSynth Update Version 1.02

App "ButterSynth"

Developer: Arto Vaarala
URL: https://apps.apple.com/app/buttersynth/id1497419006

Minimum OS Version: 14.0
Universal: Yes
Price: $19.99

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.

RELEASE NOTES: Version 1.02

  • Finally insta crash problem fixed. Which presets are new?

    LOL, when I first read this post my brain interpreted it as Sugar Bytes Factory is better than Butter Synth 😆

    (Context matters, right?)

  • Can anyone help me out with the right modulation matrix entry so that velocity does not affect volume? I could never get it working with negative modulation, which was an earlier suggestion

    one of things i requested long time ago (ability to detach velocity from volume). It’s hard coded now.. will remember this to Arto, it’s for sure somewhwre in long todo list but i think this should be prioritised

    :) thanks! But do you know if it's actually possible to counteract the hardcoded mapping with negative modulation?

    i think no, i tried it but it was not working as expected

  • Still no sustain pedal implementation. That's a shame!

    got it, thanks again for confirming

  • Mix and match.

    Would mean 5 wavetable and fm etc.

    I dont think you can switch synth engines?

    That folder was present before the update, unless some new presets have been placed in that folder?

  • You should find this version works great in Logic Pro now. I’ve been using this beta for a while and it’s stopped crashing for me entirely.

    yes, lot of new presets

    for now 5 synth engines are fixed (2 wt, 1 fm, 1 sample player, 1 granular)

    Cool tho.

    Mix and match by definition is true. If to mix and match sound

    but at a store. If there were 6 products. With mix and match. You could only buy the same 6 products advertised. So need not advertise.

  • Finally working fine in Logic Pro, also multiple instances in AUM too.
    Drambo inside AUM can record properly without ButterSynth lag. 🤩

  • Oh it’s out, nice! The beta as been working very well for me for the last few days.

  • edited September 2023

    The update has made wavetable 2 not work correctly again.

    Nothing passed the 1st wavetable updates soundwise.

    That's strange; it was added in the beta many version ago and works fine on my setup (M-Audio Oxy.Pro w M-Audio's own pedal). Anyone else having this issue?

    Edit: What do you use? iPad kind, iOS version, Hardware ...?

    Also weird as it works in beta, both standalone and auv3. What do you use? iDevice kind, iOS version?

    thanks, reported to Arto

    Nope, it does not .. it's just that wen you are in WT2 always first frame plays, even throgu you switch to other one ..

    Right. I missed tht.

  • Has jittery knobs when modulation is applied to them. Feels wobbly all in all, sometimes save button doesnt work, very strange accelerated feel to knobs like in Gadget which I totally dont like. Great synth but probably going to refund. Still thinking.

    Annoying v1.02 update Bug
    Hi,
    Has anyone else encountered this problem with the latest v1.02 update, I use BS AUv3 in Cubasis 3, every time I launch Cubasis the selected preset in BS is always different! I have rebooted my iPad Air 4 iOS16.6.1 but my selected preset still changes to one I have not selected. I have turned on the LOAD LAST PRESET SAVED but this makes no difference. If I have two instances of BS open in Cubasis both with different presets, then close and relaunch Cubasis, both instances of BS have the same preset?
    Any help would be much appreciated 🙂

  • @Sandstorm said:

    Works fine for me.

    Can you give specifics or a demonstration of it not working. If I play a note on my midi keyboard and press down on my sustain pedal, release the keyboard note, the note sustains until I release the sustain pedal.

    just tried it - no problem here.. created new oroject, loaded 2 instances if BS. changed preset in each ine, closed cubasis, reopemed cubasis, reloaded recent project - both instances correct preset

    latest ios, latest cubasis, latest bs
