PSP Spring brings three classic spring reverb emulations to your Voltage Modular rig. In addition to selecting between three spring reverb types, you can adjust the input gain, reverb tail dampening and decay time, the width of the reverb, and mix level. You can also dial in as much Twang as you want, so you can vary the spring emulations from rich and soupy to sharp and surfy.

PSP Plate offers three different selectable plate reverb emulations. You can adjust the input gain, reverb tail dampening and decay time, the width of the reverb, and mix level. You can also dial in modulation if you want to add some movement and wobble to your plate.

PSP Space is a realistic, algorithmic reverb offering three different algorithms: room, hall, and chamber. PSP Space is an easy-to-use, simple reverb module that still packs the most important controls into its compact UI; you can adjust the input gain, reverb tail dampening and decay time, the width of the reverb, and the mix level. You can also dial in modulation if you want to add an otherworldly shimmer.

PSP Delay is a bread-and-butter effect with just enough extras to make it unique. The delay can operate in mono or stereo and offers from as little as 10 ms up to 2 sec of delay. You have full control over feedback, width, and mix percentage, along with adjustable output gain. PSP Delay can sync to your host DAW and features adjustable high- and low-pass filters. That’s the regular stuff; then PSP Delay starts getting fun. You can use the PingPong control to adjust the bounce of the delays between channels. You can dial in percentages of saturation and wobble for tape-style effects and modulation. And since this is a virtual CV-controllable module, you can dial in a positive or negative percentage of CV offset for time.

This is a fully featured stereo chorus with controls for individual or grouped predelay and range times, feedback percentage, low-pass filter frequency, and crossover with adjustable frequency, along with bass boost, mix, and output level. But its real secret sauce is PSP Chorus’s output configuration switch. You can select between two to four voices and one to four LFOs, with the option to crossfeed the four voices. You can also fine-tune the chorus intensity, phase spread, and LFO type. And since this is a module, there are individual virtual CV ins to control predelay times of individual voices and control the intensity of the chorus.

PSP Flanger features a time slider from 0 to 20 ms of delay for a manual (and CV controllable) flange effect. You can adjust the width, mix, and feedback percentage controls, high- and low-pass filters, and adjustable output gain. Where it gets fun is when you control the modulation range (depth), the LFO rate, and the stereo spread. You can choose the type of modulation too, either a standard LFO or PSP’s unique wobble modulation.

PSP Rotary is an emulation of a classic mechanical modulation effect created by a rotating speaker’s horn and drum. It is a great addition and enhancement for any organ-style instrument, and for less typical applications, such as vocal choruses, strings, or even drum tracks.
