Ah I see. I may get an osciloscope at some point in time, along with the other things when I have a better cashflow.

But for now, I've come across some interesting bends/mods for the dr-55!

If a ...

Thanks, that would be great!

Do you guys think it would be a good idea to draw out the schematic in LTSPICE and test different things in there?

The only problem is I'm not quite sure how to test ...

Hey, again! So I've decided for my next project, I'm going to convert my drum machine into something I can use with my modular. I have a boss dr-55 that i got off of ebay a while back.

So far I've ...

bubzy, I just picked up an arduino, I have yet to play with it though. If it has the ability to do something like that, I'm definitely going to look into it. Unfortunately though, yeah, the arduino ha ...

This, sir, is outstanding!

Lovin' the creativity and the usability!

Well thanks for the info haha, good to know for future reference definitely.

Anyways, if any of you are interested in seeing what it sounds like with my modular/what it looks like here's the video ...

Hey guys, so I've been looking for a lower-fidelity looper schematic. The record time doesn't have to be long, I'm just looking for something really simple!

I tried the search feature but all of th ...

the LEDs are connected in parallel to the potentiometers, but:
in the schematic i don't see any LED driving resistors at all
if the potentiometers in the schematic are shown from the rear they wil ...

Well, I have a 12 position rotary switch and 2 of the positions wouldn't be used, so are you saying that I absolutely must have those positions filled instead of going to nothing?

It seems to go th ...

Thanks for the advice, i think next time around im definitely gonna draw the board out first, and also try directly mounting the pots to the board possibly? I dunno.

Anyways, I'm ALMOST THERE.

Thanks for all of the replies, guys!

So as of right now i'm gonna leave the clock in out of the picture, just until I can figure out how to get this working right.

I wired up the 555 timer to th ...

I used my multimeter to check the signal of the output on my modular.

The setting i used was at 20 V (the V with the straight line and dashed line over it). At the lowest frequency of the LFO it wa ...

Okay, sounds good, thanks for the heads up.

Interesting, thanks. Will give this a try and report back with the results. I believe i had the pulldown resistor on my old board, but we'll see.

Thanks for replying so quickly!

What's a pulldown and how would that be affecting the mobility of my steps? I read up a bit, does it basically put the pulse in the low position? I thought the purpo ...

Okay, guys. So I'm having a little bit of trouble with the sequencer I'm building.

Basically what happens is when I turn it on, the steps don't move forward. I don't know why this is having problem ...

Wow, I appreciate all of the replies, and thanks for the thorough reply, Thomas_Henry!

So essentially what I would need to do is take the control voltage from the sequencer, convert that into a pu ...

Okay, so I had a question about changing motor speed via control-voltage.

Is it possible?

Basically what I'm doing is I'm working on an analog sequencer based off of the Baby 10 sequencer. I wou ...

Ahh thanks for the reply, guys. Tim, I'll definitely go ahead and give your suggestion a try. Hopefully that will help a bit. And Jovian, I wish I would have figured that out before I ordered the NE55 ...

Okay, so I've come to a problem that I can't seem to figure out.

Basically, I'd like to have two 555 chips running at the same time, but not modulating each other. IE two square waves into a mixed ...

Okay so I've decided I want to start building a modular synth. So far, I think the most cost efficient kits I've found have been on the PAiA website. I'm trying to get a feel for what modules I should ...

o.O

i have NO idea what i've done, but i've gotten it to start taking ANY two different pitches and it ring modulates them after I soldered this together.

for example, if i use a synth and I'm u ...

Okay, so I've made a passive ring mod using the following schematic.

It works and all, but I have a 555 timer chip ring modulating a normal synthesizer, and the 555 osc bleeds through heavily. Is t ...

I am also getting this radio and static problem Sad

other than that though it sounds great! But if someone could resolve this for me, I'd be very happy Smile

Yes I'd definitely like to see how this turns out, or read up on some more info about it
