No, I didn't know about a new Raymond Scott compilation! That's great news.

A couple of years ago, my wife's grandparents gave me a bunch of 78's, one including an old Raymond Scott big band record ...

Cool.. thanks for all the great info! I think I'll map the logic switches to the resistor pins instead Smile

Thanks all for the replies..

Well, the reason is I already have the capacitor sections wired to logic switches.. I could rearrange them the other way, but won't if that will work!!

I'll keep you ...

I'm building a circuit based on the SN76477 chip, and I have a question derived from the "Sound Demonstrator Box" circuit that comes with the data sheet. I notice that many functions depend ...

That looks great! I love the colors!

For the filter, have you made sure the AR is not routed to it? When I have the AR switched (or patched) to the filter, it still passes some even when turned all the way down. I have to take all modula ...

Ray Wilson won first place for the SoundLab in the 2004 Soddy Awards:

Congratulations!

Maybe the piezo could activate the v-trig input? That's a transistor that just switches the manual gate (I believe). The voltage from the piezo to the base pin might be enough to cause the transistor ...

Yeah, if I remember right, I think the DPDT (on/off/on) switch for the LFO makes the off position default a triangle wave, and then the 2 on's have diodes to only allow the polarities of the ramps go ...

Some configurations:

SPDT is - - -
DPDT is = = =
SPST is - -

The double throw can be on/on (or on/off, depending on how you wire) on/off/on.

I'm not quite sure what you're asking... Are you talking about where to send the S/H's CV output in the SoundLab?

I haven't built this one, but usually you would patch a noise generator to the SH C ...

Wild Zebra- Thanks! Actually, yes we're from the states. North Carolina, actually. We do tour, though we haven't been up to the state that's round on the ends, HI in the middle (and home of DEVO!)

I've been building/bending/breaking electronics for 5 years or so. I have a website of my stuff at www.mysterycircuits.com

That's awesome! Will you have to reroute the switch contacts to work with the kb circuit? Or will the Kee Bass work as is?

The Kee Bass was on the Whip It video, right? But with a guitar strap?

Hey thanks!

Actually, I think you could just do 1 resistor to the 3 jacks, rather than a resistor for each. Since I used bananas, I only have single patch points that can be stacked. Essentially, t ...

Mike, a have a ? for you since yours is patchable. On the schematic do I just tap in to the point on the board i.e. like a resistor with some hook-up wire. I mean thats what I figure I do. Then for ou ...

The ground thing can be an issue if you want to interface with external gear. Unless they are both already grounded together through the audio outputs. Might be a good idea to have a banana jack dedic ...

Sounds like the AR is routed to the Osc 1 and 2 cv control. Like on Osc 1, if you switch the LFO on, you get the pitch modulation from the LFO. If you switch the AR on, you'll get a pitch modulation f ...

You don't really need a controller to use the soundlab, you can control the oscillators' frequencies with the knobs, and use the manual trigger button that will be built on the control panel. You can ...

I remember seeing a contest somewhere that was giving away an engraver a year or two ago.

I'm afraid if I had one, I'd be too laser-happy and cut and engrave everything I could find.

In a hotel ...

Wow, that faux wood panel is absolutely sexy. I'm curious about the laser engraver you used. Do you just draw up the design, and it it etches words/graphix to the surface? I've seen laser engravers, b ...

I should also point out that I did the trim-pot scale mod, and haven't had much success in getting it to scale properly with a 1v/oct controller. But I didn't use tempco resistors, and I think all the ...

It depends on whether or not each sequencer step is scaled or not (not variable)... But if each step is on a completely variable slider or pot, then it doesn't matter. What would matter is if you took ...

I did this with a 9v battery and a photo resistor. Ground the - terminal, and then run a photo resistor in series with the + terminal. Doesn't work great, and it's optic, but it gives the Theremin eff ...
