Trig Live @ Malmöfestivalen Malmö 060824

"Simon Brunndahl and Marco Manieri is trig. The setup consists of partly DIY analogue equipment (6 ch 16 step trig sequencer) and rare vintage electronics and modular synths (Roland System 100). Everything is improvised."

Synthi A Clone

Title link takes you to more shots. Kris sent the following into AH. I asked him if it would be ok for me to grab it for a post and he gave me the thumbs up. Thanks Kris!

"Thought I'd show some pics of my synthi A clone in dotcom format. It is not yet finished, but in the next months I won't have much time to work on it so I'll show you what I've got so far:

2 x VCO1
4 x VCO2
1 x Filter
1x dual ringmodulator
1x envelope shaper.

What I still need to finish:
2 envelope shapers
1 joystick module.

All the vco's switch between low and audio range so VCO2 can act also as VCO3 in the original synthi. I've also added a shape CV in and and sync in.

When everything is finished, I'll try to find a camera and I'll post a video on youtube.

Last but not least I would like to thank Yves Usson and Jürgen Haible for their help. I couldn't have done it without them!

regards, Kris"

Nice! Can't wait for the video. : )

Update: here's an MP3 from Kris.

"It's a basic patch: VCO1 and VCO2 are both in audiorange and go to the ringmodulator. From the ringmodulator it goes to the filter. Another VCO2 in low frequency range goes to the frequency input of VCO1. I manually change the shape and frequencies of the vco's and the filter."

Midibox Controllers

I realized I put up a ton of Midibox C64 posts, but none of the Midibox 64 and other controllers. Title link takes you there.

Rare Vintage Analog Synth

No title link, just shots taken from this craigslist post. Anyone know what it is? I swear I've seen it before and might even have put a post up on it. If I knew what it was, I'd search for it. : )

Details (and no I'm not the one selling it. Grab it while you can. ; )

"I'm selling an old analog keyboard, I think from the 60s or 70s. I'm pretty sure it was originally a diy kit synth. It has analog oscillators and filters with push buttons to let you change the sounds. The synth comes in a wooden case with cover, the electronics are a little shakey and work best with the cover off. The synth itself works completely, although it is shakey as mentioned and could use a little work. I've never seen anyone else selling this synth before, so I'm asking $100 or best offer."

Update: It's a Hammond Monosynth.

Roland MC-202 with Modular Upgrade by Analog Solutions

Title link takes you to a few more shots via this auction.

Details (Note the comment on Fad Gadget):
"Totally amazing box. As if the 202 wasnt interesting and versatile enough already, this one had an early Analog Solutions mod added for all sorts of options. I've photographed the box close up so you can see. I bought this from Fad Gadget, he had the upgrade added. The condition is as to be expected, its been used, but cared for really well. the sound is unique and it comes with an original leaflet all about it, a sort of user guide, a full user guide (photocopied, though) and a power supply. pay me quickly with paypal and I'll ship it anywhere in the world as you are paying. From Synthmuseum: he MC202 is a sequencer and simple monophonic synth with 32 buttons arranged like a small keyboard (F-C). The monosynth is similar to the SH-101. The VCO is based around the ever-so-popular Curtis 3340 chip and features a slider switch for octave (2', 4', 8', 16'), a slider for pulse width, and one for modulation (LFO) amount. The VCO outputs a square/pulse wave, a sawtooth wave, and a sub-oscillator which are mixed together in the "Source Mixer" section. The sub-oscillator is switchable between a square wave 1 octave down, a square wave 2 octaves down, and a pulse wave 3 octaves down. There are knobs which control fine tune and portamento. The VCF section has a slider for cutoff frequency and resonance. There is a slider for each of its control sources: envelope, LFO, and keyboard. The VCA can be controlled by a simple gate or the Envelope. The envelope is an ADSR with a slider for each stage. The sequencer is quite powerful for its time. The MC-202 features a large (for the time) LCD display, upon which all the sequencing editing is displayed. The two available sequences can be played simultaneously using the CV/gate outputs to control another sequencer. The sequences can have a combined total of 2729 events. Sequences can be entered in real time via the pushbutton keyboard or via another keyboard using the CV/gate inputs. This feature has a negative side, though. Since all incoming CV/gate signals are routed through the microprocessor, there is a bit of a lag when the MC-202 is played by a another keyboard or a MIDI-to-CV device. The Sequences can also be programmed using step-time, setting a separate pitch and duration for each note. Also programmable in a sequence is accent and portamento. Accent works the same as in the TB-303, with an accent amount knob that can be adjusted in real time as the sequence is playing. The speed of the sequence is also controlled by a knob. The back panel has a sync input and two sync outputs, a tape interface for saving and loading sequences, CV/gate inputs and two CV/gate outputs (one for each sequence), a headphone jack, and a main output jack. The MC-202 came out at a time when the synthesizer market was just starting to impliment MIDI. After MIDI became an accepted standard, sequencers such as the MC-202, using the old-style CV/gate interface, quickly lost popularity and died away."
