Analogue Oscillator

The VCO is very analogue and uses discrete components and op-amps. One oscillator, yet still sounds big - using PWM and Sub Osc creates a full warm and deep sound.

Analogue Low Frequency Oscillator

The LFO has triangle and square wave modulation signals.

Analogue Filter

Treadstone uses a four pole 24bB per octave multimode filter. The filter is a re-issue of the classic SSM2044, as used in many classic synths such as the Korg Poly 6, Monopoly, Emulator, SP1200.

Analogue Mixer

Audio signals such as the VCO, Noise, external audio are all routed to the VCF via an analogue mixer.

Analogue Amplifier

The VCA can be set so it is always ‘open’. This allows Treadstone to be used as an effects processor.

Analogue Envelope

The EG features ATTACK, SUSTAIN, and combined DECAY/RELEASE. It’s not really true to say it is an ASR envelope, it really is an ADSR - Decay and Release are both controlled by the same control. Saving space with little compromise in flexibility. It’s possible to drone or auto-repeat the envelope also.

Modulation

Great thought has been placed into modulation route choices, allowing a wide range of sounds to be produced, including percussion and ‘modular’ style sounds.
