DLP Gets ADSR x 2

I have added two ADSR envelope generators to the DLP synth. A couple envelopes go a long way! The envelope was based off a design using a 555 timer from René Schmitz

Here are some audio samples of the two envelopes modulating various parts of the DLP:
VCA and VCF
VCA and PWM
VCA and EXP FM
VCA and EXP FM running through Distortion (6 minutes of kicks)

More DLP Audio

Here are links to the audio samples and images from the initial build phase of the DLP synth from October 2012:

Audio

DLP - VCF & VCA

I finally had some time to turn back to the Dirty 'Lil Penguin (DLP) semi-modular project. A low pass VCF and VCA have been added, so the damn thing is now playable!

Audio sample here.

The sample is straight audio right from the DLP, driven by the FR-777 sequencer, and recorded via Ardour 3 on Fedora. Yes, I may be moving away from Cubase to Ardour as it can run it on a 64 bit OS and it still has drivers for the Emagic Unitor AMT-8!

Additionally I have updated the DLP github project with the latest schematics and code. Next build phase will be the dual ASDR envelopes, and then finish off the sub osc's and OSC2.

Here are some pics:

Tascam DM-24 gets a VGA port

The screen on my Tascam DM-24 has been unusable for a couple years, as probably every other DM-24 owner has experienced by now). It dies a slow miserable death as the glue on the horiz/vert connectors lets go and more and more lines cover the screen. Not fun.

So, a few years ago, after attempting unsuccessfully, to try and craft a converter that will take the LCD screen signal and convert it to VGA, I discover a guy from France at 2seemy.com has done just this, and more.

Last week I ordered this in, and 7 days later I have it up and running, like a dream and installation was so easy.

Now to reconfigure the DM-24 to do some much needed remapping!

Note the DLP synth is still an active project, and a large chunk is built, just need to do a post about it...

DLP Modular Synth Underway

Well, the file folder of schematics and notes that has been building over several years, is finally turning into something tangible. I've finally built a small rack, and the first module of the "Dirty Little Penguin" (DLP) modular syth.

Of course, the first module is a noisy mono distortion unit that leverages the CD4049 inverter chip. The circuit was based off of Stellan Lehrberg's Slowfinger guitar fuzz circuit.

Here's links to pics of the rack frame:

DLP Pic 2
DLP Pic 3

And, of course, the FR-777 was used to generate test audio. Here's two samples, the original pattern without distortion, and another with:
FR-777 - No Distortion
FR-777 - With Distortion

Next up, hopefully by the end of this weekend, the first oscillator module should be alive. This module will be based off the NE5517, which should be enough to generate Triangle, Saw, Square, and Pulse waves(no PWM yet tho).

In other news, never did pick up the Waldorf Largo. It's a nice soft synth, decent interface, and the digital distortion filter mode is quite slick. However, it didn't offer enough to justify the cost.

One synth that I did try out, with some rather tasty results, is Rob Papen's BLUE soft synth. It doesn't look like much, but the way the interface is setup, allowing you to quickly configure each of the parts, lends itself well to creating nice stereo pads, drones, and effects. The filters available are quite good, a bit smooth in that Rob Papen style, but lend themselves well for creating very detailed and wide sounds, in a way that I haven't really seen in any other synth except for some Reaktor patches ;)

2010 - Studio Alive Again

After moving to a new house in the country, outside Ottawa late last year, the Igloo studio is now up and running again! Gear is set up, and the new room has been given a rockwool treatment which has done wonders for the sound. This is currently the smallest room I've ever been setup in, so a bit of sound treatment was essential. With any luck, and a bit of time, should have some new releases for 2010 for both Calibrated and Blizzard!

The Igloo has already had a couple local Ottawa boys through with some productions, including DJ Dain-Ja

Also, a new CPU (AMD Phenom II - 940) for the main studio box is also on its way, which should give a bit more power with its 4 cores and slight clock speed boost.

Gigs and Gear

Gigs: I'm playing out a hard techno set as phaXis at DFF tomorrow night (Saturday, June 6th) here in Ottawa at the Cock and Lion on Sparks. First time playing that regular club night and its rare that I play techno sets east of Winnipeg, so it should be a thumpin' night to remember!

Gear: Since the local shops here seem to be delayed getting their hands on the Waldorf Largo, and since Moog Audio in Montreal looks like they have stock of the new builds of Future Retro's XS, disturbingly awesome synth, it looks like that the XS and not the Largo will be landing next in the Igloo!
