Well, the cat's out of the bag
Fine, this isn't the pun thread. I'm excited that I can finally start sharing details.
Here's an abandoned version of the manual. I restarted it from scratch with a completely new format, hyperlinks, table of contents, better typesetting, etc. That one's not ready to share yet. However, if you want a list of the oscillator/mix modes and details, this will give you a great idea of what is inside: https://www.dropbox.com/s/xfm7f72nxdg54 ... l.pdf?dl=0
Every oscillator mode has unison depth over every control, except for the Superstacks. Those modes are designed as optimized unison modes.
Every oscillator mode also has an optional Stereo mode. In each mode, the algorithm is tweaked for wide stereo output. The width of this can be tamed or exaggerated with the BYOME row's Stereo Image effect.
There isn't a wavetable mode. Frankly, the market is jam-packed with wavetable synths, and we're not interested in adding another. Serum, Massive X, Europa, Hive 2, and Ableton's Wavetable are all very good implementations, just to name a few.
Our main design goal for LION was to create a low-floor, high-ceiling synth where people can create their own presets very quickly just by turning one or two knobs. However, with the many modes, the BYOME row, and the modulation system, the presets can be extremely detailed and complex. We didn't want to create a synth where people would get lost on Envelope Tab 5, the voicing tab, the micro-option to enable some esoteric behavior, etc. In that regard, LION was designed without tabs, alternate screens, or layout changes. Everything is visible on one screen, and all oscillators, filters, and mixers share a unified interface design.
Not listed in the manual: filter modes.
LP/HP/BP12: The filters from Indent/Dent/BYOME's Basic Filter, now with an optional DRIVE control (All filter modes have an optional DRIVE toggle for non-linear processing along with an INVERT button to mirror the topology).
MS LP/HP: Sallen-Key (MS-20) style, lots of resonance and aggression
Acid Filter (LP): 303-style. Very nasally and squishy
Ladder LP/HP/BP 12 and 24: Moog-style. Different model than the one in BYOME to accommodate all of the different slopes and topologies.
SVF LP12/HP24/BP24: OBX style
Someone mentioned "Braids + BYOME". Yes, a good way to think of the workflow is "2 x Braids + Warps + Filter + BYOME". We didn't use any source code from Braids/Plaits. The only two models that are pretty direct versions of the Braids models are Ringo (similar to Triple Ring from Braids) and VOSIM. VOSIM was built using a recipe from the SOS Synth Secrets column, but with some added FM features of our design. "SumSyn" is based off of a Summation Synthesis algorithm listed by Stephen McCaul of Noise Engineering. In the mixer section, "Compare" uses a few of the comparison algorithms in Mutable's Warps, but rewritten for our codebase, and most of the "Terrain" algorithms were generously shared with us by Aaron Anderson (http://www.aandersonportfolio.com/wave- ... sizer.html
), a PhD student at our alma mater, MAT @ UCSB. These credits are all listed in the new manual. Emilie Gillet has been a huge influence on our design goals, so I want to make sure that she gets proper credit, but I also want to make sure that people are aware that this isn't a Mutable clone.
Finally, what does "LION" mean? We've joked internally that LION is a recursive backronym, "LION Intermodulated Oscillator Network," which is an accurate description of the behavior, but that wasn't the intent. Really, LION is a visual pun. LI is a square wave, O is a sine wave, and N is a sawtooth wave.
Anyway, back to preset design!
