"Frostwave Resonator with the following features:
HP Res: controls the resonance of the high-pass filter.
HP Freq: controls the frequency of the high-pass filter
Level: controls the output level of the effect.
Balance: mixes the "dry" signal with the "wet" signal.
LP Res: controls the resonance of the low-pass filter.
LP Freq: controls the frequency of the low-pass filter
The Frostwave Resonator is a very versatile analog filter. It can take any weedy sample, loop, mix or instrument and give it some fat analog tone or some crunchy lofi grit.
It can create filter sweeps, from subtle to extreme, generate booming sub bass, and take any standard instrument or signal and give it an "analogue" sounding treatment- run a flat drum machine or sound loop via the resonator and you will get big analog drums and samples on the other side....
The Resonator can also self ossicate, creating spacey, atmospheric sounds on it's own without any input source. Combined with other effects some amazing and unique sounds can be generated."
"Frostwave Resonator with the following features: 
"The Frostwave Quad MIDI-CV Plus is a rare rack mount four channel MIDI to analogue CV converter made in Australia by the now defunct Frostwave company. The unit operates in three different modes including as a basic four channel CV converter where it interprets MIDI note number, velocity, and note on/off on any four adjacent MIDI channels and produces corresponding control voltages and gate voltages to control up to four analogue mono Synths. 
The Frostwave Blue Ringer is a true bypass box, with the standard ring mod controls of a wet/dry mix and oscillator frequency. There is a level control for the input signal, as well as a second input signal (allowing Input B to become the modulation source for the main input) and a blend control, determining the mix of the internal oscillator and Input B as the modulation source.
