Erica Synths DB-01: 12 patching ideas

video by Richard DeHove

"A look at some of the obvious and not so obvious things you can do to get a variety of sounds. Especially important is the use of LFO phase shifting, something which was introduced in firmware 1.07. It has a dramatic effect on the sound in both note reset mode and pattern sync. At the end of the video I get in some random noodlings just for fun.

"We drive along a section California Highway 4, the John Muir Parkway, between the I-80 in Hercules and I-680 in Concord. It winds through picturesque hills in northern Contra Costa County before taking on a more suburban character around Concord. It is a major commuter route, but quite nice during off-peak hours.

Big Boom Demo
Swizzle Circuits Tripple Attenuator Module Demo
Swizzle Circuits Opto Gate Demo - EuroRack Module

Big Boom

We went back to basics again with our twin Op-Amp designed circuit. Tuning knob will take you anywhere from deep Kick to high Tom sounds. The Decay adjustment will get you from a quick hit to a self-resonating bass drone. A ..::boom::.. button lets you preview the sound or play by finger. Gate In is sensitive enough for most triggers and a LED indicator lets you see when it booms.

Powered - 6hp (30mm)

You get exactly that... a Big Boom. You might need to become better friends with your neighbors after you install a Big Boom or 2 in your rack. Turn down the Tuning and Decay adjustments and just let it rumble. Then again its not hard to tame this beast..Tuning and Decay in the mid range makes a very recognizable and amicable kick drum sound that will drive any melody into something that will make you want to move your body. Manual trigger button on the face lets you play by finger to add just the right low end push to your creation.

Just like every Swizzle Circuits module, it comes fully assembled, tested and ready to go. Just take it out of the package and plug it in.

Big Boom EuroRack Module features:

includes power cable.
Install more than one for multiple drum sounds.
LED indicator shines through the face to let you see the action.
Decay adjustment goes into a self-generating bass drone with wave re-triggering for rhythmic stuff.
..::boom::.. button allows you to manually trigger the Big Boom for preview or free play.
Gate In is tuned to accept most CV gate triggers, sequencers and LFO signals.
Swizzle Circuits custom designed PCB

Tripple Attenuator

Some of the most basic modules always turn out to be the most useful! At 8hp, this module is small enough to fit anywhere, but big enough to give you full precise control. Grab all three at the same time during a big break! The LED indicator lets you know that your signal is staged right where you want it and ready to be used. Attenuation works just as well to tame unruly LFO, envelope and other CV signals. Just like every Swizzle Circuits module, it comes fully assembled, tested and ready to go. Just take it out of the package and plug it in.

3 fully independent rows of attenuation ready for mixing and fading audio sounds or limiting CV signals. All channels include luxurious 45mm sliders with LED indicator at the tip to tell you when there is signal at the inputs. Linear range control with total cut off at the bottom and full pass through when the slider is at the top.

Tripple Attenuator Module features:

8hp (40MM) non-powered
45mm linear taper sliders with red indicator LEDs at the tip.
Non-Powered to fit in anywhere.
LED indicates incoming signal (audio and CV) at a glance.
Swizzle Circuits custom designed circuitry and PCB

Dual Opto-Gate

Seems simple; lots of uses! Similar to Vactrol control, the analog microchip this module is built around has been used for decades to switch isolated circuits and transfer high-speed signals. We took that ability and put it into a passive module that somehow has Gating indicator LEDs that show when the Gate is ON. How did we do that? Hmm. Just like every Swizzle Circuits module, it comes fully assembled, tested and ready to go. Just take it out of the package and plug it in.

At the heart of this module is the ILCT-6 2-channel opto-isolator. Full analog gating with nothing to get in the way of your signal. Inputs can be audio signals OR CV control signals. This little wonder can gate well into the audio range allowing some simple frequency modulation. Gating signals can come from an LFO, envelope, or sequencer.

Module Features:

- 2 fully independent Gating channels.
- Non-Powered; fits anywhere.
- Gate ON indicator LEDs on each channel.
- Very minimal Gate ON resistance.
- Capable of Gating into the audio range for frequency modulation
- Gating follows LFO or envelope shape. Swizzle Circuits custom designed PCB and circuitry.

Using the CV-A and CV-B control inputs, you can shift or "scan through" the 4 signal inputs and outputs. This can be done smoothly or in steps, depending on the Control Voltages you're feeding into CV-A and CV-B. In this video, we'll show you how to set up your CVilization module accordingly. And of course, we'll be walking you through the Ins and Outs of Matrix Rotation (pun intended!)."

"XPression - the tool for the creative musician
DynaSample has been striving to build a bridge between acoustic and electronic sound generation. The goal was not only to create an instrument that would simply sound good. It was most important that playing it would have to be easy and intuitive. It had to work without keyswitches, lots of pedals or other external control items. Nevertheless it should be playable immediately in realtime without spending ages of practicing. On top of it it should have a comparable expressiveness and musical bandwith as only known from real instruments up until now.

After years of development we have succeeded to create this instrument - due to "Voice Control" and "TDB".

Here is XPression - the next generation of electronic instruments!

I just tested everything before packing up and the unit is in great shape, no issues found. This model has the patch panel as well as CV & Gate outs in back...MIDI too. I was using the CV & Gate outs to control my 777 and the audio input for the filter. Nice!

Tom serviced this back sometime between 2010-2012ish when the input level knob went. Been rock solid since."
