We’ll soon be offering the Grendel DC-2e Drone Commander 2 in a standalone format. It comes with a custom fitted Eurorack case. The case features a removable lid, tolex vinyl covering, and convenient power supply. Orange and black finish are standard options; custom colors available by request.
Synthesizer demo with Grendel DC-2e Drone Commander 2 Eurorack and Grendel RA-9 Grenadier. Two tracks of DC-2e, one track of RA-9, plus a touch of mystery synth. Grendel synthesizers are available from I/O Music Technology, Detroit Modular, Switched On, NoiseBug, Perfect Circuit Audio, Analogue Haven, Noise Kitchen, and SchneidersLaden.
Demoing the Grendel RA-9 Grenadier and DC-2e Drone Commander 2. A sequenced LFO effect is obtained by patching the Grenadier’s sequencer output to the LFO CV input of DC-2e. The track was composed with MIDI in Reaper DAW software, using a 4-channel MIDI-to-CV converter to interface the analog intruments. The analog snare drum and bass drum are new prototype designs in development here at Rare Waves…
This video walks through getting started with the Grendel DC-2e Drone Commander 2, beginning with using the Main Module by itself (0:30). Next, see how to control it from a MIDI keyboard, using the Expander module and a MIDI-CV converter (3:40).
A self-patch that gives additional filter modulation is demonstrated (5:35). After that, one of the MIDI-CV converter’s auxiliary CV outputs is patched in to control DC-2e’s LFO rate with the MIDI mod wheel (7:00).
The next section demonstrates VCF 1’s self-oscillation (8:35), including how to cancel the filter’s self-oscillation so only the dry tone of the VCOs is heard (9:50). Then, VCF 1 is set up as a third oscillator, creating a constant-pitched drone note to accompany melody played on the VCOs (10:50).
Last, some examples of pitch modulation using the MOD knob are shown (11:40), leading to full-on crazy town.
Rare Waves LLC demonstrates a Grendel Drone Commander 2 prototype in Eurorack format.
Drone Commander 2 is a true analog synthesizer with discrete transistor technology. It has 12 knobs for lots of hands on control, and every knob is a push-pull switch for lots of tone modification options.
It retains the original Drone Commander filter, and adds a second independently controlled filter for contrast. The second filter is a smooth and clean 4-pole lowpass filter (-24dB/oct VC-LPF). It has an attack-release envelope generator and serves as a lowpass gate, to control the volume and tone.
The LFO section has been completely revised.. its kind of hard to describe, listen instead (please pardon the noodling)
The optional Expander module can be connected for extensive voltage control. It has 18 patch points including CV/Gate input, Clock in/out, and external audio input. Connecting a MIDI controller and MIDI-CV converter to the Expander gives the Drone Commander 2 its full potential for melodic control, sequencing, and synchronization.
A stand-alone version may be in the works also. More audio at soundcloud.com/rare-waves
Grendel Drone Commander 2 Eurorack is in the works.. Now with CV-Gate and Clock inputs! In this recording of the prototype, it is sychronized to MIDI using a Vermona QMI. The Roland TR-808 is running with a Doepfer MSY2 MIDI-SYNC converter. (Dope riddims by Erich Ragsdale)
Comments Off on Drone Commander 2 Prototype + TR808
‘F-Sharp Fantasy’ .. All sounds in this track were created with the Grendel RA-9 Grenadier semi-modular analog synth. We used Reaper for MIDI sequencing, and a Vermona QMI for MIDI-CV conversion to control the Grenadier by CV-Gate. One Grenadier was used in creating this track, and the composition was built up in layers through overdubbing. Grenadier’s onboard trigger loop sequencer was used to alter the gate pattern of the bassline to add variation. The only non-stock sounds are the whispery percussion effects created by connecting a pink noise source to the Grenadier’s EXT.IN jack. 2015 Rare Waves LLC.
