PSP Ultimate Modular Collection: 30 Modules for Voltage Modular by Cherry Audio

The effects side covers familiar studio staples. There are three spring, three plate and three room reverb emulations, a digital delay with tape modulation and ping-pong modes, and a four-voice stereo chorus. A stereo flanger with manual control and a rotary module emulating a mechanical speaker horn and drum are also included. For dynamics and EQ, the pack adds a VCA-style compressor, a ten-band graphic equalizer and an analog-style parametric equalizer.

The pack also includes a dual formant filter, a pitch shifter, an analog-like frequency shifter, a phaser with up to 32 stages and a continuously variable bitcrusher with presets.

Several modules focus on control signals rather than audio processing. These include a dual envelope follower, an LFO offering ten waveforms or derived waveforms, an advanced envelope generator and a multi-stage envelope generator. Polyphonic utilities such as a polyphonic VCA, a polyphonic patch bay and a module that controls random analog-style instabilities add more routing options.

Filter options cover a dual parallel filter, a two-channel comb filter, state-variable filters, and a fourth-order ladder-type resonant filter. A multi-stage signal folder and a noise generator round out the sound-shaping tools.
