Hi,

Does anyone have any spare PICs and PCBs for sale? I really want to build one of these!

Hi,

I want to build the following amp and preamp, but I'm unsure as to what capacitors are electrolytic or not, since there are no marking on schematic to suggest what cap to use. Also, how can I c ...

Thanks for all the replies!

I'm using a mac, so won't be able to used FreePCB, can anyone recommend something else?

Thanks again!

Hi,

Could anyone recommend me a cheap company that can manufacture PCBs, preferably from PDF files?

Thanks!

Brilliant, thank you for the links!

So can the RM 1x be used as an external sequencer without using it's preset sounds?

Sorry, I meant storing sequences. Edited.

Hi,

I am looking for a digital CV/ Gate sequencer that can store sequences allowing me to switch from one sequence to another. I already have a few analog sequencers and find it quite difficult to ...

Hey,

So I tried running a wire from the sequencer ground to the ADSR ground and still no luck. I have the ADSR wired up to the long version.

Any other ideas?

Brillant, this looks good! I managed to find the MCP on the microchip.com site, however there is a minimum order of 5.

So could I run a banana jack from the sequencer ground to the ADSR ground?

Thanks again!

Thanks for the reply.

Since the ADSR and sequencer are two separate units they don't share a common ground.

Is it possible to add something to the gate in on the ADSR as to reduce the gate pulse ...

Hi,

I want to be able to use a midi keyboard to play chords on my modular, essentially making it psuedo-polyphonic. Does anyone know of any DIY solutions to be able to do this? Basically I just nee ...

Hi,

So I'm having a problem using the gate switches on my MFOS 16 step sequencer when using the Yusynth ADSR v.2. When I turn a gate pulse off on the sequencer the ADSR still sends out a gate pulse ...

Opps I meant to say TL074. Thanks, I'll check the soldering.

I just noticed that when I power it on the output of the waves is a lot louder, but gradually decreases over a period of say 5 seconds. ...

Thank you for the reply. Wiring seems fine. I'm getting a negative reading from the pulse jack, is this normal?

Should I replace the TL7041? Pin 8 is reading -13 V.

Thanks!

Hi,

So I just put together the VCO, I haven't tuned it yet, but all other waves seem to be working apart from the sine and square which are very quiet. Any ideas on why this might be?

Also the L ...

Catch 22, how can I build one without the capabilities of matching resistors before hand? Unless someone could send me two, I would pay of course.

Thanks!

Anyone?

This may be a better choice then, as it has 19999 count display and 4 1/2 digits. What do you think?

Thank you for all the great advice, it's all very helpful! Turns out that the meter is not functioning as it should. I was thinking of purchasing this:

This may seem like a really stupid question but how do you match resistors?

On all of my meters the value seems to fluctuate and doesn't remain on a single resistance value, so what would be the b ...

Finally, a digital CV/ Gate DIY sequencer! Does it store patches and do you have a rough date in mind for release of the schematics?

I'm really looking forward to this!

Looks great! Will it be CV/ Gate?

Thank you for the reply!

I was looking for something that used multipole connectors via a distribution board so I could connect it to all my modules.

Hi,

I'm just about ready to start ordering parts for a modular I am building. It's only going to be a 22U modular.

The power supply I require is +/- 15 V. I don't want to use a wall wart, as I w ...
