SOUND: The SSM2040-based Z2040 has a wide range of sound quality, from fat and transparent to distorted sound.Gain, resonance, cutoffYou can create a wide range of tones by combining the three knobs. In addition, this filter puts the audio signal into the FM input andFilter FMYou can produce a particularly punchy sound when you perform.
Self-oscillation:The sine wave sound generated by self-oscillation is difficult to match the pitch to the scale because the FM input is not 1V / Oct specification. Instead, with the Z2040, you can cut the sound by sending an envelope from the VC-GAIN to the built-in VCA.Percussive sound source based on sine waveIt is suitable to use like.
VC-FM: One of the features of the Z2040 is the VC-FM input. This is the input for "modulating the modulating signal", which modulates the CV signal to FM in. This allows for example
- Audio rate CV → FM in, attacking envelope → VC-FM in: Sound that filter FM is strongly applied and attenuated only at the moment of attack
- Relatively fast LFO → FM in, slow LFO → VC-FM in: Filter modulation sound with a gradually changing intensity. Drone sound with richer movement when used in combination with VC-GAIN.
- Envelope → FM in, voltage corresponding to velocity → VC-FM in: Acid sound in which the strength of the filter envelope changes in response to velocity
Both FM in and VC-FM in are equipped with an attenuator knob that adjusts the amount of modulation, making it a compact size of 8 HP and a module with quality and versatility that is easy to use!
PHYSICAL STRUCTUREThe core of the Z2040 is the SSM2040 chip, but what is worth mentioning is that it has more modulation options than the original chips of the 70's and supports modern usability.
Built-in VCA The Z2040 has a built-in VCA, and you can set it on the front stage or the rear stage of the filter by setting the back jumper. Since the VC-GAIN input is connected to the CV in of this built-in VCA (figure below), not only the frequency and resonance of the Z2040Gain can also be CV controlled. If you want to control the amount of filter distortion with CV, place the built-in VCA in the front stage, and if you want to use it as a clean output VCA, place it in the rear stage.
The settings for each case are as follows.
