[sdiy] ASM-1 copyright? Gene?

[Gene Stopp]

Hi Jaco (and list),

Full green light!

The ASM-1 is a totally open design, mostly done by others anyway. All I did
was make a PCB so you could buy it if you did not want to go through all the
hassle. (it's really the panel that takes up most of the project anyway!) If
somebody out there makes a better PCB than I did, I would probably buy
some!!

It's probably a good time to mention to the DIY list that I will not be
sourcing the ASM-1 anymore. I've got too much dad stuff going on to be a
reliable source. 3 kids, oldest 8th grade, youngest preschool, some of you
out there probably know what I mean :)

Here's what I've prepared to send to any new incoming inquiries:


Hello,

The ASM-1 project has been a lot of fun for me over the last seven years.
However, the demands of my family are increasing and I am finding it hard to
keep up with all of the inquiries that come in about it. In the interest of
keeping this project alive for the international DIY community, I've
officially handed off the production and sale of the ASM-1 printed circuit
boards to another enthusiastic and capable fellow who is able to keep up
with the demand. He has the original PCB artwork and so the PCB's you
purchase from him will be identical to those that I have been shipping out
all this time.

Inquiries for purchase of the ASM-1 can be sent to the following email
address:

boobies at ozemail.com.au

When you purchase the ASM-1 PCB, you get:

(1) Blank circuit board - doublesided, etched, soldermasked, drilled, and
silkscreened with component location markings, ready for stuffing with parts
that you provide. All required components are available from electronics
suppliers or other hobbyist sources.

(1) Set of documentation - Schematics, parts location drawing, and text
containing theory of operation, assembly notes, and application suggestions.

The ASM-1 is an analog synthesizer voice which consists of the follwing
modules:

(2) Voltage-Controlled Oscillators, exponential response with optional
tempco resistors. Inputs for frequency (1v/oct), pulse width, PWM, linear
FM, and hard sync. Outputs are Sawtooth and Variable-width Pulse, -5v to +5v
(10v amplitude).

(1) Voltage-Controlled Filter, exponential response with optional tempco
resistor. Inputs for frequency (1v/oct) and audio signals. Outputs are
Lowpass, Bandpass, Highpass, and Notch simultaneously. Response is 12db/oct
(2-pole) state variable with adjustable resonance.

(2) Voltage-Controlled Amplifiers, linear response. Inputs for amplituded
control and signal (inverting and non-inverting). Output for signal out.

(2) ADSR Envelope Generators

(1) LFO with Triangle and Square outputs

(1) Noise Source with White, Pink, and Random outputs

(1) Glide Processor (portamento circuit)

Power requirements are plus and minus 15 volts, at about 80 milliamps each.



- Gene

Uhm, gene? Magnus?

Actually, i asked the question a while ago, but i'll ask it just to
make
sure i don't waste the efforts made...

Clean and simple: Can i release the Stripboard-layouts of the ASM-1
on my site (http://synthsite.8m.com) without screwing the money you
earn out of the PCB-Design / efforts made to make this synth even
exist?

I won't even think of putting the layouts of the stripboards online
if i don't get a full green light on this, okay...
