Sonicsmith Convertor

   (0 reviews)


The first ever, semi modular, Audio Controlled, analog synthesizer.

The ConVertor is our first and smallest of our ground-breaking synthesizers. With a simple 9V power it can turn analog audio input into analog synth waves and CV outputs.

With our revolutionary Audio Controlled Oscillator, the ConVertor is capable of synthesizing two wave forms as well as extracting the pitch, envelope, gate and trigger CV signals from analog audio input.

The ConVertor’s main audio input can receive audio at line level, instrument level and even dynamic microphones with a clean preamp gain of +40db range. A switchable 2 pole HPF and a sqeepable LPF can help the user with isolating the fundamental frequency if such help is needed (ie. more complex harmonics audio is fed). The ENV is generated via an ENV follower on the main input or via the 2nd ENV follower on the "side-chain" input separately if you wish for more control over the level behavior of the synth. Two 4 character LED meters will reflect the input level of the main audio input and the side-chain input separately. The envelope amount knob can dial between fully following the input envelope through "no envelope" in the middle position and even reverse the envelope by dialing the knob to the left.

The ConVertor will play square and sawtooth waves together which the user can blend continuously via the WAVE mix knob. Two knobs can control the harmony interval of the synth within a 5 octave range on a just tuning scale. Octave CV and Harmony CV inputs duplicate the knob’s functions but enable the user to arpeggiate the synth from any external CV source like an analog sequencer or an LFO. All CV outputs are accommodated via 2 stereo minijacks and a thru jack duplicates the input for further chaining of other audio controlled synths and simply for recording direct instrument.

Single ACO design

Extracts gate, pitch, envelope and trigger CV signals from a single audio input

Plays internal analog synth with both square and sawtooth waves along with the input

Input HPF and LPF can be used if help with pitch tracking is needed

Input preamp design with clean 40dB range3 thru jacks duplicate the main input, side-chain input and CV inputs for unlimited daisy chaining

Side chain minijack input can feed the second ENV follower for alternative ENV pathEnvelope shaper with continuous control from positive to reverse shape

9V battery operation or standard 9V pedal supply

Dual level meters for main input and side chain input
