[sdiy] Analogue sequencer & Juno 106 VCF

[Luis Marka]

I've been lurking here for a while, and this is my first posting to
the list. Hi all! OK, I have a couple of projects I am about to start
building (these will be the cornerstone of a Frankenstein modular in
the future), and would like to know: has anyone built the analog
sequencer published in Practical Electronics (March 1979), by Lindsay
Robinson (link to the project here:
http://omega.tellus.vallentuna.se/anders/seque.html , "p.e.
sequencer")? The schematics seems to have a few handmade mods, around
IC10 in Fig3.tif, and I don't know if these are corrections or what.
The other project is: my Juno 106 blew a couple of hybrid VCF modules
(800170), and as far as I know, it´s only their VCAs that end up in
Analogue's Heaven (or hell, if they misbehaved when alive...). As I
replaced these modules for new ones, now I have two filter chips
available. Well, I want to build a dual VCF module, and again I would
like to know if anyone already did that using such ICs.

Well, that's it for now. Seeya, and greetings from Brazil,
Luis Marka
