note: due to the high-quality and flexibility of the filters in the gemini, it is recommended that a Pulsar 2 board (or more DSP) be used; however, users with a Pulsar 1 board can use the gemini with one-note polyphony (many presets are included especially for monophonic use, such as basses and leads). the gemini will not load onto a Luna (2) board.

specs:

VCO
- 2 multi-mode oscillators per voice, each with: sine, triangle, up saw, down saw, square (with pulsewidth), and an external input setting
- both oscillators allow for extensive modulation capabilities to control pitch, pulsewidth and cross-modulation (see features)
- the second oscillator can be hard-synced to the first

VCF
- 2-stage filter (in series): flexfilter to 2-pole filter mixer

- both oscillators first pass through the hummel 'flexfilter': 1-pole, 2-pole and 4-pole filters can be selected, each allowing for lowpass, highpass, or bandpass
- lowpass, highpass and bandpass levels can be freely mixed with eachother
- cutoff and resonance knobs control all filters simultaneously (allowing for notch filter variations, etc); 1-pole filters do not allow for resonance control
- the filter levels can be mixed with an unfiltered 'dry' signal, direct from the oscillators
- all filters can be simultaneously fedback into themselves
- the flexilter allows for extensive modulation capabilties to control the cutoff frequency (see features)

- both oscillators then pass through the 2-pole filter mixer (in series from the flexfilter output)
- lowpass, highpass and bandpass levels can be freely mixed with eachother
- cutoff and resonance knobs control all filters simultaneously (allowing for more notch filter variations, etc)
- these second filter levels can be mixed with a signal that is not filtered by itself (flexfilter only)
- this second filter mixer also allows for extensive modulation capabilties to control its cutoff frequency (see features)

VCA
- amp envelopes for each oscillator, individually + a final amp envelope that mixes both
- individual level controls for oscillator 1, oscillator 2, tuned noise and white noise
- final amplitude control before output, includes volume + boost
- the final volume controls can, again, be modulated extensively (see features)

- global controls: coarse tune, fine tune, portamento/ glissando, pitch bend range

EFFECTS
- includes 'crusher', ringmodulator, stereo chorus and stereo phase shifter

- 'crusher' gives a low-fi, grainy and noisy texture to the output signal

- the ringmod has its own mod oscillator. which can be morphed from a sine to a punchy down-saw
- wet and dry levels can be mixed, as well as a non-filtered ringmod signal
- the control oscillator can, itself, be controlled by a dedicated LFO

- a standard and subtle stereo chorus is provided

- the chorus outputs are fed into a custom stereo phase-shifter (developed exclusively for hummel products)
- the phase-shifter allows for a wide array of timbre shifts and complex tuning variations

FEATURES...

- modular-style routing, extremely flexible, but without all the wires and sprawling surface panels
- clean, intuitive design and layout
- ultra-smooth control functionality (no zipping or popping)
- authentic analogue-style sound capabilities
- flexible mod-wheel control over amplitude, pitch and each filterbank
- almost all functions can be controlled by the gemini's unique and powerful modulation matrix:
velocity
aftertouch
osc 1
osc 2
white noise
tuned noise
key follower 1
key follower 2
ADSR 1 (which itself can be modulated by the other mods)
ADSR 2
multi-mode LFO 1 (the frequency can be modulated by the other mods)
multi-mode LFO 2
multi-mode LFO 3
envelope follower
