News from Synthtech, a Fracrack version of the MOTM 510 wavewarper is in development, with a projected availability of August this year. As you may know, fracrack versions of some of the MOTM modules are exclusively available through the Analog Haven store in CA. This wavewarper will be no exception.

My own Wavewarper (full size version) hasn't arrived yet, but I am not in a hurry. First still awaiting my second VCO, which should be shipping in the next few weeks, but I am guessing April sometime. It will be more fun warping two VCO's through the Wave warper, than just one, so this shipping order works out fine for me.

MAC version of updater

Okay, perhaps a little early to report, but me being a Mac user, I am happy to report that Synthtech has found a programmer willing to write a Mac version of the Updater program, used to update the MOTM-650 midi-CV converter.
When it will be ready is unclear at this point, but if you want to be a Mac beta tester for this updater program, then write Paul a note describing your OS (it will be OS X only, no Classic, or OS 9), and your midi interface model etc.

Robert Rich demo

A new Robert Rich MOTM demo is available on the following link.
Below is the report from Paul Schreiber.

Robert Rich

MOTM-480 on the "bass drops", MOTM-650 sequenced playing the Wendy Carlos Harmonic Series tuning table (3-note polyphonic with delays), MOTM-510 on the very high "wind chime" tinkle bits. MOTM-440 on the lead and pads.

Robert plays PVC flute from Home Depot ($6.80 total cost).

Prototype case

Well, it took some time, but here is the first revision of my case, actually it's the top half.
I don't have that many modules yet to be building a base under this one, so that the total unit will look like a VCS 3 case, as reported a while back.
I build it with MDF, to get some practice and get an idea on how large the unit would be, and where any problems could be.
Some dimensions, it fits a 19" rail, outer dimensions are, 54.4cm wide, 46 cm tall, 36.5cm deep (at bottom) and 20 cm deep at the top. The front is angled at 20 degrees, which is a nice slope.

MOTM 440 sound

So, how does it sound? Judge for yourself. I've posted a familiar bassline (familiar to those who listened to an earlier demo from me) and gave it the MOTM 440 treatment.
1 vco used, which sends a TRI wave on input 1 of the filter, a Pulse wave on input 2, and the MOTM 101 sends a noise source to input 3, i mix around with these a bit on the 440. The pulse width of the PULSE wave is modulated by an LFO, and so is the cut of frequency of the 440. However I keep tweaking the Freq, and REs knobs on the filter, a little.
The whole deal has a little delay and reverb mixed in for good measure, but other than that nothing. Enjoy.
It can be found in my MOTM sound sample link to the right :-)

Oh just in case you forgot, the original recording was done with a 420 filter, A B comparison illustrates the different characters of these filters, where the 420 is squelchier, the 440 sounds fatter and smoother. I love both. :-)

Picture time

Here are the pictures promised.

First my synth with the 101 module and 440 front panel installed.
Second, the heavily populated pcb of the 440.
lastly, the the important part, using silicon heat paste to thermally attach the tempco resistor to the CA 3086 IC.
