EMS Synthi A mk1 reverb/outboard PCB w/ rare GEL234F1 ICs

via this auction

"bought new from papz/portabellabz a month or so ago. only taken out of packaging to take these pictures

The board brings the very sought-after typical MK1 sound with more low-end and a nice overdrive at high output levels.
The top part is a replica of the most recent PSU circuit with an added +11V rail for powering amp ICs as in MK1 units.
The bottom part is a replica of the original MK1 output amps and reverb driver circuits.

the board comes calibrated and ready to use, swapping with the original one is straightforward, no soldering or modification or calibration is required."

ADSR Card Long Attack

video upload by Todd Barton

"The Portabellabz ADSR/LPG Card can create longer envelopes than the Easel's EG. Here I haven't even maxed out the Decay, Sustain & Release parameters so I'm guess longer envelopes are possible. Enjoy!"

ADSR:LPG Card Playdate

video upload by Todd Barton

"My first day with the new Portabellabz ADSR/LPG Card. Just trying out a bunch of different things as I begin to learn it. Thought I'd share these impromptu explorations. When released they can be ordered here:
My Patreon:"

via Mod Wiggler

"The card features a versatile analogue VC looping ADSR (AS3310 based), a preamp, a LPG and an output mixer.

It's an ideal companion for the VCS3 Card or Triglav's Radio Receiver one to add a full 3rd voice.


LED : monitors the ADSR output

Attack : sets the attack time
Decay : sets the decay time
Sustain : sets the sustain amplitude
Release : sets the release time

Black banana CV inputs
Attack : controls the attack time (attenuator trimmer easily accessible next to the pot)
Decay : controls the decay time
Sustain : controls either the sustain amplitude or the pulse length (see below), selected with a mini slide switch
Release : controls the release time

Buchla 208 & 248 with Portabellabz Synthi EMS VCS3 Oscillator + Toolbox + BOB

Published on Dec 19, 2019 isvisible isinvisible

"Trying out the Portabellabz EMS VCS3 oscillator.
Nothing complicated, just a touch of noise mixed in with the square and triangle, and a smidge of waveshaping.
It's accompanied by the 208 Complex Oscillator doing the plinky plonks.

All with a little dab of the on-board Buchla spring reverb and a Bugbrand PT Delay."
