Subject: Re: Why not breadboard a small MOTM sequencer?

From: "Paul Schreiber" <synth1@...

How about a small sequencer design contest? On paper, a 2U or 3U wide panel.

Design it out, scan it or fax it to me (817-498-3782) and I'll eye-ball it.

In fact, there is no 'winner'. What I'll do is summerize each one.

Here is a good MOTM Module Sequencer Calculator (not what I use, but it will
give you an idea)

Baseline cost = $65 (pcb, res/caps/ICs, wires, brackets, overhead, profit,
blah blah blah)
Panel adder 1U = $12, 2U = $22, 3U = $36
Each pot/knob = $10
Each Switch = $5
Each jack = $4
Each LED = $3

Difficulty factor

Easy = 1X
Not that hard = 1.2X
Pretty hard = 1.6X
A Mother! = 2X

So a 3U wide, 8 pot/8 LED with a manual STEP button (counts as a switch),
int CLK pot,and
EXT CLK IN, 1 MASTER CV out, 8 individaul stage jacks (gate/trig cv
whatever) would be.....

65 + 36 + 9x10 + 5 + 8x3 + 10x5 x 1.2 = $324 kit price (roughly!)

In reality, there are games to play with the pot quality (shudder!), but the
point is that sequencers
can get expensive quickly in the MOTM way of thinking. Note that it really
does NOT matter
what the exact nature of the electronics is: this is the rule in every
module so far (the VCO is
another story!). The cost everyone pays for is NOT the electronics: it's the
quality of the pots, jacks,
and panels.

Have fun!
