DESCRIPTION

I’ve always admired classically-styled modular instruments, particularly the ones sold by synthesizers.com. But my aversion to having to tear apart a cool-sounding patch to create the next one ensures that I’m unlikely to ever buy a true patchable analog modular.

So, here’s a modular synthesizer for Reaktor, based on modules available from synthesizer.com. It’s designed to fit in a 44-module walnut cabinet. A few of the modules are modified or enhanced to suit my whims. The modules included are:

1 MIDI Interface
1 Slew Limiter
1 Noise Source
6 Voltage-Controlled Oscillators
3 Voltage-Controlled Filters
2 8-Input Mixers
1 Sample/Hold
2 Control Voltage Processors
3 Voltage-Controlled Amplifiers
3 ADSR Envelope Generators
1 Fixed Filter Bank
1 Voltage-Controlled Pan/Xfade
1 Ring Modulator
1 Shaper
1 Voltage-Controlled Delay
1 Oscilloscope/Voltmeter
1 Stereo Output Mixer
1 Stereo Output Chorus

Module inputs are visualized as drop-down menus which display the available module outputs. Modules don’t consume CPU cycles unless actually used.

The operating voltages mimic synthesizers.com modules. For example, oscillator outputs swing between +5 and -5 volts, and envelope generator peak voltages are +5 volts.

There are no LFOs. In the style of synthesizers.com instruments, oscillators double as LFOs.

Playing modes include polyphonic, monophonic legato, and monophonic retrigger. Monophonic and polyphonic portamento are built into the pitch controller.

Four assignable MIDI busses are included.

Two extra mod matrix outputs are available (labeled Extra1 and Extra2) so that two additional modules can be added to the system without having to modify the mod matrix.

V2 update: I've connected the pitch wheel, which wasn't wired up. If you want to fix this without downloading the update, go to the "Inputs" macro and draw a wire between the pitch wheel multiplier and the adder to the right of it.

V3 update: The instrument now has a wonderful new skin created by Jonathan Style. The internal circuitry is unchanged, so existing snapshots can be loaded into this version with no issues.

Good koncept. Just the way one could imagine it should be. But the snaps dispoint. Hope there are more under the hood. Would have benn nice with a few killer snaps to get startet. Thanks.

Great synth, limitless possibilities, great for beginners to experiments with modular synths. Only downside is the filter area which isn't much represented (one fixed filter bank). I guess we can use the extra 1/2 inputs to plug in an external filter though.

Hi, Doss, and thanks for the comments. The mixers are actually 8-input mixers, and inputs 4 and 8 don't have knobs. Their architecture matches the 8-input mixer offered on Arrick synthesizers at http://www.synthesizers.com/q113.html.

really like this modular - it's super logically laid out and sounds good. I was curious though, in the mixer 1 and 2 labels it would appear the second column knobs indicate input 5,6 and7. Should these be input 4, 5 and 6 for those 3 corresponding oscillators? There is obviously a LOT of meticulous work on this synth - thank you for sharing.

this Looks amazing. can't wait to try it out.

one of the best still. tie this baby to a monoline sequencer and you're in it.

Wow! This is just wonderful. Thanks!

After a bit more tinkering, I've come up with sort of a half-assed solution re: the peak EQs--I changed the core cells' F inputs from Audio to Event and inserted an event smoother with a transition time of 3ms before them.
Sandy Small 3 years ago
Needles to say, this is a superb piece of work. There are a few issues I should point out though--with a filter set to 2-pole LP/BP/HP or or any of the peak EQs, modulating the cutoff frequency with an audio rate signal results in an NAN error followed by processor overload. Swapping out the SV C filters for SV T filters (and scaling back the resonance slightly--I multiplied it by 0.98) takes care of the 2-pole filters and sounds essentially identical. I haven't found a satisfactory solution for the EQs, and I don't have nearly the DSP knowledge to fix it; however the problem seems to be occurring in the little feedback loop in the IIR stage. (Also, 'Fixed Filter Bank' has a typo)

I also just soiled Tom Cunliffe with joy. *wipes Tom off*

Yes, it is. The Wall was too big for me to have fun with, so I wanted to shrink it and focus on a theme. And since the synthesizers.com stuff always appealed to me, I decided to focus on that.
Bernd Keil 5 years ago
Is this ensemble the further development of 'The Wall'? Great!

I just fell of the toilet seat laughing at the last comment. This synth is completely BS free! And an old minimoog love like me just can't praise enough. EXCELLENT

buttons and knobs, oh my! Thanks for this beast. It's worth the price of admission for the Glidy Oboe snap alone!!! I'm gonna have to set aside along weekend to play with this!
