Subject:Re: MIDI Drawbar Controller for B4

Hey Steve,

Wow, and here I thought I was the only guy working on one of these!
I have an old gutted model A that I am in the process of converting
to a B4 rig by way of Jordan's B4CE board. I like the A for this
project because the cabinet is a bit smaller than the B3 (but the
manuals are the same).

I already ordered my B4CE, and it should be here any day now. Got a
bunch of the other electrical parts from Jameco--potentiometers,
diodes, switches, etc.

I'm curious--what are you planning on for your drawbar setup?
Jordan's setup pretty much mirrors the B4 layout, which differs from
the hammond drawbars. Most notable among these differences is the
lack of 2 'switchable' sets of drawbars (i.e. through the preset
keys). I was thinking about wiring up my drawbars through some
simple relays to allow for 'hardware' switched drawbar assemblies via
a switch (since I'm using the manuals for a midi matrix). I'm
thinking about leaving my preset keys in place, and using one of the
nine bussbars for a preset switching matrix. If I toss in a ten
position rotary switch to feed into the B4CE, I could get up to 80
presets (not the 120 offered by B4 but close enough!)

Let's talk about computer hardware and wiring!

Later,

Jude
