MOTM 440

I have finished my MOTM 440 module. For those of you who aren't entirely familiar with this module, in short it is a discrete VCF that mimics the filter used in the Sequential Circuits Prophet 5 v2 synthesizer.
I don't own a P5, so I can't compare it, but what I do know is that is sounds really nice :-)
I am going to post pictures of this filter being build soon, as I made a few during it's construction.
I did come across two issues that I did not experience before. First was that I ran out of organic solder, and second was that some holes were a bit to tight. Let me explain:
This particular module is probably the most populated circuit board from all the modules I've made so far, on the same area as some other modules, there are loads more components, including 13 transistors, and 14 IC's! It came with just as much organic solder as all other modules I've build, and I ended up running out during one of the final stages of using this type of solder, about 5 transistors into adding the ehh well transistors, one of the final steps before switching to non clean solder.
Lucky though that from previous kits, I had enough left over, in fact, one roll was hardly used so it seemed, so I could finish the module without problems.
The second problem was having difficulty getting the jacks and pots in the holes on the front panel. I never had that before on these MOTM kits, and the problem was easily solved , it seemed the paint coating on this module is a little thicker, and after carefully scraping some out of the holes with a sharp knife, the pots went in, but not without first having a pot stuck in it's hole, and nearly snapping it of the pcb by accident when trying to push it back out carefully......
Anyway, all ended well, and I have a great new filter module to put through it's paces. :-) Piccies AND sounds to follow. :-)

Here's what I've been up to, I am preparing to start the 440 filter module this weekend, and I've mounted the 101 noise/sh module among the the others in what is slowly maturing in to a nice 'little' modular synth.
So yes, pictures will follow soon, for both projects, and I'll be making some new sounds with them and post them here too.
Also nearing completion is my design for patch sheets, once done, I'll post these so you can easily copy the sounds I'll be creating......

Stay tuned :-)

A little update on the shipment status for those who are still waiting for some orders:
Paul Schreiber reports that due to Presidents day today, there are no mail services, so he can't ship today. This will be Thursday now, and he will ship approx 26 modules / kits. Then last week february, first of March, another 60 will follow, which will go a long way towards 'catching up' as he states.

It's about time I start on my 440 kit, so that I don't get too far behind. I still expect a VCO and a Wavewarper, and a patch panel. When these arrive, my synth is 2/3'rd done :-)

MOTM community

It's fun to be involved with MOTM. I've now made contact with two different people who are in my work area, that also own an MOTM synth. One of which I am going to meet this weekend hopefully.
This is another aspect of the synth hobby I like. Great fun, go on, start building one, and meet new friends. :-)

VCO's and more.

We are on our way into the new year now, and my postings have been rare of late.
This was because I was out of town for business, and had very limited internet access, and when present, at depressing low speeds, so updating my blog was not very easy, sorry.
Anyway, the news on the MOTM front can be wrapped up as follows:
Work on the new Synthtech website is delayed, due to a 'real job' change by Paul Schreiber, the limited spare time he has left is going to be taken up trying to ship all out standing orders. (I still have a 910, a 550, and a 300 in that list), with the priority givien to the VCO's in the month of February. Hey, that means my second MOTM 300 VCO could be coming at any given time now :-)

But first I'll start building my MOTM-440 VCF, as that is still laying in a drawer waiting to be unpacked and build.... Guess I'll be doing some reporting on that in the next week or so.
