Roland TR-77 voiceboard in 19" with midi trigger interface

Stereoping
Published on Aug 15, 2017

"More or less entertaining demo- and testsong with slideshow for a project in summer 2017: putting the voiceboard of a broken Roland TR-77 drumbox into a new 19" housing and supplying a midi trigger interface to overcome the boring preset rhythms. The board offers 13 pure analogue sounds, mainly generated with big coils in stunningly simple schematics: Bassdrum, Snaredrum, Hihat, Cymbal, Maracas, Tambourine, Low Conga, Low & High Bongo, Rimshot, Cowbell, Clave and Guiro. Guiro is more kind of sound effect producing a permanent chirping sound in 2 different frequencies. It's fully supported by the interface: 2 different midinotes switch Guiro on/off and high/low.

I also found a very simple way to misuse the onboard VCA for an accent feature. The VCA normally mutes the TR-77 output when stopped to prevent getting all the noises from the clockgenerators to the output. (The Accent feature is just explained, not demoed in the video.)

All drumsounds in the song come from the miditriggered TR-77 voiceboard running through a TAPCO 4400 stereo spring reverb. Further equipment: Juno 6 + Line6 Echopark, Korg Polysix + Roland DEP5, Kawai K4 and - at the end of the vid - a lovely diletantic live synth solo on the minikorg-700 through the realtime tweaked Sparta Delay.

The beginning of the song is quite cheesy but stay tuned, around 3:20 it turnes into a nice 80ies style. Hope you like it :-) Wanne see more midified drumboxes? Then please drop a comment. I still got many of them flying around, waiting to be brought back to studiolife by getting some midi-trigger support.

I also wrote an article about this project on my site: https://www.stereoping.com/tr-77-info..."

Cool command center style case. See if you can ID all the gear. There are some obscure pieces in there. When you are done guessing you can check some of them out in previous posts from prinztronix here.

New GRP Eurorack Demos

The following have been added to the playlist in this post.

9. Grp Synthesizer Low Frequency Oscillator
"Four Grp Low Frequency Oscillators; each one drives VCA Gain amplifying a filtered oscillators. LFO rates are uncorrelated and each LFO can vary its waveform from ramp to triangle and from triangle to saw."

10. Grp Envelope Generator Euro Rack
"From left to right: first eg on PWM, second eg on cutoff frequency, third eg on cutoff frequency (with double ratcheting gate), fourth eg on amplifier."

11. Grp Mixer Euro Rack
"The inverted Oscillator ("-" out of the left mixer) is subtracted (e.g., added with minus sign) to lowpass filter output... instant high pass filter. :-)"

Modular synthesizer vs LesPaul goldtop (braids, rings, ears, peaks, maths, morphagene)

Lately I have been experimenting with external equipment processed through my modular, it is turning out to be way more fun that i initially anticipated. :) on this one i have a les paul goldtop copy exciting the Mutable instrument rings.. providing very interesting results.

It is a very simple patch technically, Mutable instrument ears gets a signal from the Guitar which has a pre-driven distorted sound processed in the Line6 FX100 ( on the floor, not visible )... clean overdrive with no other FX. However I am controlling the volume of the guitar using a swell pedal on the same.

The signal then goes from ears into the MI rings, to excite the resonator, rings in turn has 1v/Oct sent to it on scale E and D minor in a pretty random fashion, but simple enough to play melodies on. The rings is then modulated by a could LFOs for some movement.

I am also splitting the ears output to a separate path, that goes into the morphagene for some sound on sound treatment that plays the guitar back in reverse with some granular treatments.

Techincally i have two styles of the sound which I am switching between by just controlling the output signals.

Drone sound is a simple 3xsaw that goes into the ripples first, whcih has a slow LFO adjusting the cutoff, then it passes into the uVCF which has a triggered envelope in the maths controlling the filter controlled randomly by the 2hp turing machine. So whenever the ripples is opening up, you can hear the uVCF bubbling away.

MI peaks is doing the drums, controlled by the beatstep pro.

FX on the drone is Keeley caverns, FX on the guitar signal path is EQD space spiral and transmisser.

On top of it all i am also playing a melody on the KORG volca for some moody ambience, treated by particle reverb algorithm in the ms-70 CDR FX.

If you become a burgonaut patron, you can see a video how this track was made + more goodies and extras from the BURG vault of secrets.

I hope you will enjoy it!!

BoOoM!"
