I got my hand on the latest BleepStreet iOS synth “Zeenon”. It uses a very high quality algorithm to simulate analog synth circuitry. So much that it can only runs on 64 iOS devices.
From BleepStreet site
Features
- Audio Unit v3 and standalone application with a simple polyphonic step sequencer.
- 2 oscillators with continuously variable waveforms, hard-sync and sub-oscillator. Carefully simulated analog drift and PSU influence.
- Filter: 3 models available: Transistor ladder low pass, OTA cascade low pass and State Variable Filter with continuously variable LP-HP + BP mode.
- 2 low frequency oscillators and envelope generators per voice.
- Overdrive: diode clipper and transistor saturation, pre and post filter.
- Up to 2 layers per voice. Layers can modulate each other.
- Powerful modulation matrix offering self-modulation and cross-layer modulation, 8 modulation slots, 17 signal sources and 41 targets available, both from modulation modules and audio signal path. This takes Zeeon into semi-modular territory. Imagine oscillator waveform, panning, filter cutoff, resonance or LP-HP mode modulated by oscillators or another layer!
- Effects unit: Circuit modelled BBD chorus, bass booster, zero-delay Phaser, Stereo delay and Reverb.
- 144 presets and Tutorials bank, more coming soon.
