The MEQ-5 based on Classic Mid-Range Equalizer from the '70s, with two bands of midrange boost and one band of midrange dip, the MEQ-5 gets the very best out of the «power region» where guitars and vocals can make or break a mix.

The EQP-1A based on Classic Program Equalizer from the '60s, original EQ is renowned for its unique ability to boost and cut the same frequencies simultaneously, thereby creating a resonant shelf, the EQP-1A faithfully models the overbuilt transformers and complex tube amplifiers of the original hardware.

A highly tweakable stereo delay AudioUnit effect, suitable for everything from clean digital delays to filthy dub echoes, flangers and broken cassette tapes.

Hammond B-3X is a next-level tonewheel organ app.  We’ve partnered with the Hammond Organ Company and Suzuki Musical Instruments to create the most immersive, authentic and powerful B-3 experience for use live on stage or as a plug-in inside recording apps.

Photon AU - Midi Recorder with Pad playback & Groove. Record your midi performances using this audio unit in your DAW then save/export them as standard midi files via email or directly to other apps.

Polythemus AUv3 Midi was created for five main uses: сreating a polyphonic synth from individual monophonic synths, stacking different or similar synths that play alternatively for variation, interesting variations in timbre & rhythms by having multiple synths driven with a sequencer (e.g. Quantum) or arpeggiator, work outside IOS on hardware synths, voice allocation of externally hosted software vst(e.g. Logic or Ableton Live) using mac osx IDAM for direct device to mac midi.

So what is a midi echo? It is similar to the audio echo effect where copies of the original audio are repeated at regular time intervals but with some form of change (e.g. quieter). But unlike audio, midi is digital in nature (low resolution 8 bit mostly) and focused around the midi note on & off message used to control synths etc.

The EQ550 faithfully captures the punch, low-frequency transparency, and ultra-tight imaging of iconic American EQs of the late 1960’s.

Based on Classic American EQ from the late '60s, the EQ550b is a continuation of the EQ that played a major role in the history of music recording, but with an additional filter band and several new frequencies.

In the '80s it was the first to use a different approach to tonal adjustments. In conventional analog equalizers, whether they are shelving, sweepable, graphic or parametric types, various sections of the audio spectra are boosted or attenuated by adding or subtracting bandpasses. In this case, frequency shaping is achieved by summing bandpasses.

Does your bass sound dull and lifeless? Red Rock Sound Bass Enhancer will be your choice to correct this deficiency. Bass Enhancer designed for saturation harmonics of low-frequency, it creates the effect of lower, deeper frequencies. This effect can not be created with simple equalization.

The EQ-A based on Classic British EQ from the '70s. With a wide range of tonal variations, the EQ-A is an audio tool with great flexibility and sonic ability.

The Red Rock Sound Exciter will allow you to improve and enhance sonic quality of signal more naturally than with equalization. Unlike traditional EQ that just turns up the existing harmonics, Exciter generates additional harmonics, therefore there is no boost in the output signal level, this maintains a clear and balanced sound.

Comp 609 is a compressor AUv3 plug-in.

PolyIvoks Filter developed on the basis of the filter of the legendary Soviet synthesizer from 1980s, and only now the legendary Soviet analog sound became available in stereo mode.
