Most parameters in Driver have their own two-stage envelope, each of which can be set using Driver's interactive display. This way, every oscillator's volume, pan, and pitch has its own independent envelope, along with each filter's frequency and resonance, each effect's depth and level, the LFO's rate and depth, and lots more. With 22 parameters each having their own envelope, it just takes seconds to create complex evolving sounds. And with 150 patches included, inspiration is even easier.

Features
Sound Engine
Driver features three oscillator banks:
a traditional waveform oscillator (sine, triangle, saw, and pulse width waves available);
a seven-oscillator supersaw with adjustable depth and width (each with their own envelopes);
and a noise generator with variable color (with it's own envelope).
All three banks also feature variable volume, pan, and pitch settings, each with their own envelopes. The oscillator and supersaw generators also have an octave selector with a five-octave range.

Filters
Driver also features two multimode filters with high-pass, low-pass, band-pass, and band-reject modes. Each filter includes variable cutoff frequency and resonance parameters, each with their own envelopes. Each sound generator can be routed to either filter, both filters, or neither filter.

Envelope Timing
The duration of each stage of the envelopes is variable. When free-running, each stage can last between zero and 20 seconds. When tempo-synced, each stages can last between 16 full measures and a single 128th note. Driver also features four latch modes, so that you can determine how each stage of the envelope responds to key presses and midi notes.

Modulation
Driver features an onboard LFO and step sequencer. The LFO contains six waveforms (sine, triangle, square, random, reverse ramp, and ramp), can be free-running or tempo-synced, and has variable rate and depth parameters, each of which have their own independent envelopes. The step sequencer can have between one and 16 steps, can run at resolutions from 8th notes to 32nd notes, and have variable attack and release parameters for the steps. Both the LFO and the step sequencer can be routed to any parameter's envelope, and each routing can be individually trimmed.

Effects
Driver contains on-board reverb and saturation effects. The reverb's depth, and the saturation level both have their own independent envelopes.

Additional Envelopes
Driver contains two more independent envelopes, each of which have their own CV outs on the back of the device. These can be routed to other devices in Reason, or can be routed back into Driver to modulate other envelopes.

CV Input
Standard CV In gate and note connections are provided. Additionally, Driver contains four generic CV In connections that can be routed to any of the 22 independent envelopes.
