About this app

Ens1 is an “ensemble” virtual synthesizer, paying homage to (and improving on) classic “paraphonic” instruments such as the ARP Omni, Polymoog and many Italian-made ensemble keyboards. These instruments, though not as complex as later polyphonic synthesizers, excel at creating sounds reminiscent of strings, choirs and brass though also capable of creating wholly synthetic sound textures.

Ens1 features:
2 Tone “Generators”
Continuously-variable wave forms from Triangle to Sawtooth to Narrow-Pulse to Square.
Simultaneously-available 16’, 8’, 5 1/3’, 4’ & 2’ ranks.
Generator detune.
Pitch LFOs with frequency, depth and “frequency spread” between generators.

3 Resonators
Frequency, resonance & gain (including negative gain) controls.
Bypass, Low Pass, Band Pass, High Pass and No Pass modes.

Paraphonic Low Pass and High Pass Filters
Frequency and resonance
LFO with separate depth for low pass and high pass filters
