Grendel 2TAC analog sequencer with RA-99 Grenadier

This video demonstrates the Grendel 2TAC 2-track analog controller with the Grendel RA-99 Grenadier analog synthesizer. The Grendel 2TAC has two tracks of CV-Gate output (1v/oct). For synchronization, it has an internal tempo generator, analog pulse-per-step Clock In/Out, and Reset pulse In/Out. This video tutorial shows some of its pattern editing features, time stretching, creating pattern chains, altering the tuning, mashing several patterns together simultaneously, and generating random patterns. We will be offering a limited issue of the 2TAC as pictured in the video with black aluminum case, walnut sides, and red or yellow LEDs. For visual reference, this version comes with the key commands printed as a graphic on the underside of the case.

Grendel Formant Filter V2.2

We have brought back the Grendel Formant Filter eurorack module for 2022. This voltage-controlled analog filter effect produces vowel tones by subtractive synthesis using a bank of four bandpass filters. Version 2.2 is available now and features several choice updates. The control panel now comes in your choice of brushed anodized aluminum in silver or black. Electronically, this version now includes a 3-way Mode switch offering a convenient bypass function, as well as the new MODE 2 which adds a 5th analog filter to the effect for fuller bass response. MODE 1 is very similar to the sound of the original.

Grendel DC-2, Formant Filter, RA-99 Grenadier

Key of C minor, tempo 84 BPM.
This synth demonstration from Rare Waves uses the Grendel DC-2 as a tone source. Grendel Formant Filter provides vowel filtering, and Grendel RA-99 Grenadier is performing the LFO duties. Rare Waves Hydronium is used as a MIDI-CV converter to set the pitch of the DC-2’s oscillators. In the picture you also see a prototype Polyphonic Strobe Tuner, which provides a real-time pitch analysis. Also heard in the mix are our prototypes of a Surf Sound Synthesizer and Spring Reverb.
