Ancient Passage

video upload by davidryle

"This basis of this project was between the new Synthetic Sound Labs 1655 Geo-Gruvn euclidean sequencer and a few different Low Pass Filter modules. The new SSL 1015 LPG with the cadmium sulfide CdS element, the Mega Ohm Audio CdS VCF/A module and the Cyndustries Quad Low Pass Gates module. The Cyndustries module was enhanced by Phil from Mega Ohm Audio to be much more responsive. A big change and very useful.

The Geo-Gruvn module from SSL is an adaption of the Hagiwo board and was also enhanced to provide a more efficient response all the way to audio rate clocking.

The main orchestration automation module in this piece was with the synthesizers.com Q170 Midi Gates module. The use of eight channels of midi gate streams from Cubase were the way each section were enabled on and off. My hands-on modulation was simplified to allow me to change timbre, filter settings and delay rates with ease.

The center section featured the Dove Mu-Seq D900 sequencer for a pattern which began by me running the sequencer in reverse and recording the track to Cubase, then reversing it back into the mix. I started with the Woven Spirits (MI Plaits) at a higher octave and drew it down until it matched the timbre for the rest of the midsection.

The last part was the dual Matrix run into a pair of quantizer modules in which I timed the pitch voltage outputs with the Geo-Gruvn gate outs. These voices were the Dotcom Q206 and Q206A modules through the Frequency Central X Series Low Pass Filter and an Empress Reverb pedal.

Other delays included the Modcan 73B dual delay with loads of modulation, and the SSL 1310 Digital Delay.

The opening drone is a feedback from the TipTop Audio Z-DSP VC-Digital Signal Processor with the Halls of Valhalla chipset in Plate Reverb mode. This drone also arose in the center section.

A pair of frequency shifter modules (Encore Electronics and Behringer Bode Clone) were used for the Snare and Hi Hats enhancement. The kit drums were the LDB-2E Analog Drums from Delptronics and the TipTop SD808. They were sequenced from the Mutable Instruments Grids module and a pair of Turing Machines and an MI Marbles module."

MOD2 Prototype test | Seeed XIAO RP2350 based Drum module for eurorack

video upload by HAGIWO

":Almost all of the programs were generated by ChatGPT.
Since the circuit has been simplified, there are few CV inputs and the audio is output via PWM, but the RP2350 is fast enough that even a simple program can produce reasonably good sound.

Although there are no plans to use it as a VCO, it also supports V/oct.
