Nope, sorry. $4 less :)

OK, 4X gate delay DIY board is now on sale until midnight PST Tuesday Feb 09, 2010.

The details:
GD-B= Gate delay Assembled/tested board only= $64.95
GDK= Above board with the wire kit and power cable of choice=$80.95
To get it into my head, suffix the GDK with a -6(6P-6P power cable), -4(4P-4P power cable) or a -E (4P-Euro power cable)

So, the full kit with a 4-pin to Euro-style power connector would be:
GDK-E

Once again. This is a MW only offer so, you'll have to PayPal me direct to my PayPal account:
mattsonminimodular(at)comcast.net (at)=@

US shipping add $4.95 for up to every four boards.
Everywhere else, add $13.50 for up to every four boards.

You guys are crazy :hihi: But thanks a lot!!
I just ordered the new boards for this so, 2-weeks and we'll have pretty new boards.

Oh, yeah...when you order, let me know what your MW username is so I can match up orders with usernames. Tnx.

Does the 4x 1x2 Buffer also buffers cv signals above 5 volt?
I love to use it with 10 volt cv range.

Yes it does. It will recreate anything you feed into it up to a few mV shy of the power rails. It's also bandwidth limited to the capabilities of the op amps so, It sucks for anything RF related :lol:

Seconded! This is great - sending my payment for this extra module and a VCF later tonight or tomorrow!

Richard, any chance of us seeing the FPD file for the VC Mixer panel you designed? Just heard from Scott and it's going to be at least another 6 weeks before Bridechamber has them - might not be able to wait that long. I designed one but curious to see yours.

Thanks!

I came up with a 1U wide 5U panel that uses the jack grid from the standard MOTM format. It's 8 x 2 positions that can take a 16mm alpha pot with 3/4-inch knob, a 1/4-inch jack, an LED, or a toggle switch in any position. I even put small tick marks around the pots. The main problem with these (as all) FPE panels is that they are in the $50.00 ballpark! I'm also building two CGS modules in this panel format. One is done and should be getting onto my website soon, maybe this weekend, with photos. Then it'll be easier to explain this panel design.

You guys are making me blush. :eek:

If it wasn't for all of you, I wouldn't be doing this. The respect goes to all of you. :hail: :clap:

Thank you.

BTW

If anybody here has the ba--, er, wherewithall to attempt my VCO or MIDI-CV controller, email me and let me know.

The MIDI is really cool and has some unique features plus, a hidden menu for setting pitch bend up and down ranges independently, mod rate and depth, glide direction, gate number, one-way gate triggering, upper/lower/last note priority and glide-only when multiple keys are pressed. Panel controls let you choose glide rate, stepped (almost arpeggiated-valid MIDI notes only) or smooth glide, fixed time and normal octaves/sec glide and has a handy mod output that outputs 0-5V DC in response to the keyboard mod wheel rotation. The thought being that it can be used to control a channel (or channels) on the Voltage controlled mixer so you can control a CV or audio mix with the mod wheel. The other two outputs are CV and gate. The MIDI can be set to respond to any of the 16 MIDI channels or put in MIDI standby. Pressing both channel up and down buttons simultaneously for >2 seconds will latch the gate on for drone-type operations.

It's not a hard board to mount. It's 2X size of the standard boards and has a ribbon cable connecting the display. The ribbon cable is just long enough to wrab around and mount the display on the back side of the board. I could make some longer ones if desired.

It also has a connector for hooking up a switch to turn your DC power on or off from the front panel.


The VCO is a slightly oversized board but requires some point to point wiring on the panel components, a multi-turn trim needs to be mounted/epoxied to the panel for the V/Octave trim and is a PITA to calibrate.

I would consider them advanced DIY projects. Which is why I haven't offered them.

But, It's a good challenge for advanced people. After getting to know some of you, I'm sure the talent is out there.

Just a thought


George

I just got that panel today from Front Panel Express and I haven't even opened the box yet! The style is just like this one:

http://pugix.com/synth/cgs-slope-detectors/

You can download the FPD file there.

For the VC mixer, there are 4 pots in the upper left with the 4 input jacks to the right. The 4 VC input jacks are on the lower left, and the OUT and INV OUT jacks on the lower right. There are two unused locations. The Buffered Multiple with Attenuators uses the same layout, with eight output jacks.

I'm actually waiting for some Bridechamber 3-jack brackets I'm going to cut down in length and try to mount the Mattson boards to. The boards are just a tad too wide, but I can jerry-rig it.

Ah, I saw you link to this earlier but was confused...should have read more closely, sorry about that. This is great, though - my design is 2U and I'm reaching a point where space is really starting to matter. Thanks for sharing!!

Is anybody thinking of doing a FPE (or other) 5U panel for the Gate Delay?

I'm working on one. Have a 2U wide design but might try to make it work within 1U. Not sure with all those LEDs, pots and jacks, though. I can post the 2U version this weekend if you'd like.

Outstanding!

I was mentally trying to lay one out, and couldn't come up with a practical way to make it fit into 1U, what with 5 pots and room for LEDs. But I have no real experience with designing panels so perhaps there's a trick I wasn't able to envision.

Would love to see what you've come up with.

Ok, I'll upload what I've got tonight. It's the 2U version and possibly still a work in progress - just whipped it up the other night.

Ok, here goes. The 4 spots above the 4 output jacks are for the 4 corresponding LEDs. Check the size for the LED holder you plan to use - this is for the pre-built assembly that Paul Schreiber at MOTM uses. The spot next to the Input jack is for the "gate on" LED.

That looks NICE Luka.

Are you going to use 7211's to switch the output modes?

I originally did that and realized that you can use the HP on one channel panned far..one way and the LP on another channel panned the other way and use the mod input as a VC panning function. It's still LP on one channel and HP on the other but a cool patch.

I'd like to see how you fit all 3 boards behind that :)

You're welcome. Really wish I could squeeze it into 1U but don't think I can. Curious to see if anyone else is up for that challenge 8_)

Haven't had a chance to power up my PC to look (I'm generally on a Mac)...will hopefully do so today.

There are 15 components on the Gate Delay: 5 jacks, 5 pots, 5 LEDs. Those can all fit with one spot to spare in the 1U panel format I've been talking about.
