"3 analogue vcos (sawtooth, square, triangle waveforms)
2 envelope generators (adsr)
analogue 24 db lowpass filter with resonance (vcf)
2 lfos (sawtooth, square, triangle, random waveforms)
50 preset- and 49 user memories
integrated step sequencer
the mfb-synth ii is a monophonic synthesizer module. it uses analogue circuits that are voltage controlled for oscillators, filters and amplification. the synthesizer is controlled by midi, cv/gate or the integrated step sequencer that can hold up to 25 sequences with 32 steps each. here are the details:
the vco sections contains three individual oscillators that are scaled to the volt/octave standard. the selectable waveforms are sawtooth, square and triangle. vco ii offers an additional impulse wave and pulse width control for the square wave. the octave can be set between 4', 8' and 16' or 32'. an additional detune amount of plusminus one octave can be set for vco 2 and vco 3. the vcos can either be modulatied by an lfo or vco 3. vco1 can be set to sync and two digital ringmodulations are available as vco1+2 and vco2+3.
the mixer allows level control of all oscillators plus noise and the level of the external audio input. the lowpass filter is a resonant 24 db/octave design. emphasis (resonance) can be set up to self oscillation. the cutoff frequency can be automodulated by an lfo or by and vco. key controls the influence of the keyboard pitch on the cutoff parameter (keyboard scaling). both vcf and vca have their propietary envelope generators with attack, decay, sustain and release parameters. the vca can also be modulated by an lfo for characteristic tremolo effects.
there are lfos. the waveforms offered are sawtooth, rectangle, triangle and random. the can be set to „one shot“ mode to be used as simple envelopes. the mfb-synth ii 50 preset- and 49 memory locations. the synthesizer will respond to incoming velocity data (midi). the velocity information can be used to control either vcf cutoff or vca level. pitch- and modulation wheel are both recognized. the step sequencer sends and receveives midi clock and responds to start and stop midi commands.
connectors: midi in/out, audio in/out , cv/gate in, power"

Nord Lead 4 Sound Init & Arpeggio
Published on Feb 16, 2014 AudioCentralMagazine·191 videos
"Nord Keyboards Nord Lead 4 offers a deep and powerful synth engine, with a couple of audio oscillators (one, with preloaded, non-scanning, wavetable), digital efx and a lot of modulations. Sadly, no channel aftertouch, no 16x2 display and no encoder... but, cutting corners is OK for keep down price."

Delta Music Research Polyphonic Modular System 1100 SN 003

"DELTA MUSIC RESEARCH STUDIO SYSTEM 1100
POLYPHONIC ANALOG MODULAR SYNTHESIZER, SERIAL No. 003

This is my fantastic Delta Music Research Studio System 1100 Polyphonic analog modular synthesiser. Built in Canada it's thought by ex-Moog technicians, there are very few of these systems in existence and this is Serial No. 003. It's probably the only one in the UK, though there are other users still in Canada and the USA.
The 1100 has all the advantages of an analog modular system and none of the disadvantages. Firstly although it appears modular, you don't have to install modules individually as they all share a large control panel circuit board, so there's no fiddly screw mounting system. In any case it's hard to see why you would ever want to change any modules when you have this great specification -
4 x Voltage Controlled Oscillators (switchable audio/LF)
4 x Voltage Controlled Envelopes
4 x Voltage Controlled Amplifiers
2 x Low Frequency Oscillators
2 x 4-channel mixers
2 x Voltage Controlled Filters
White/Pink Noise source
4 x Voltage Attenuators
6 x Multiples
Balanced Modulator
Inverter Summer
Voltage Controlled Flanger
Springline Reverb
Because the system has four of most modules and comes complete with a microprocessor controlled four-voice polyphonic keyboard, it's designed to play as a polyphonic analog synthesiser comparable to a polyphonic MiniMoog or an Oberheim 4-Voice. But mostly you'd use it in monophonic mode, and with the ability to modulate oscillators at audio frequencies and add voltage controlled flanging, it's capable of some incredible abstract sound textures. It's easily the equal of an EMS Synthi VCS3 in terms of being able to create and sustain its own evolving, clangourous and metallic sonic landscapes.
The system cabinet is 24.5 inches wide so this is a much more impressive object than the usual 19-inch systems. As such it would make an incredible centrepiece for an advanced analog or sound effects programming studio. Included also are the keyboard, box of patch cables, and 110V convertor for use in the UK (this powers both modules and keyboard).
Physical condition is very good. Some minor marks on the black tolex covering. One knob cap damaged but working (it may take you half an hour to spot which one).

Madrona Labs Aalto 1.5 Now Available
via Madrona Labs:
"Hi all! This winter has seen a flurry of programming here at the labs. Aside from finishing up our new synthesizer, Kaivo, I have done some work fine tuning Aalto and making sure it plays nicely with recent operating systems and hosts.
Aalto 1.5 is out now. As always, you can get the release version by logging in and clicking “My Downloads,” and the demo at the Aalto product page. Version 1.5 has some major compatibility improvements for both Windows and Mac users. Performance should be dramatically improved on some Windows systems. I’ve improved the usability of the Patcher and dial UIs.
On Mac OS, if you have a Retina display, you are in for a treat. As always, you can smoothly scale Aalto to a wide range of sizes, or even zoom it to full screen. This new version has a new OpenGL-assisted renderer so graphics are amazingly sharp, at full Retina resolution, in compatible hosts. It may be “only a graphic thing” but I find this change means that using a tiny little Aalto window is now possible, which can really improve workflow on a laptop screen. (note: unfortunately Ableton Live does not yet support full-resolution rendering.)
Here’s the list of major changes in Aalto 1.5:
Fixed an issue that was slowing down Aalto dramatically on some Windows systems.
Fixed an issue requiring a runtime support pack on some Windows systems.
Improved latency through the patcher when running at large host buffer sizes.
Aalto now draws at full resolution on Macintosh Retina Display, in compatible hosts.
Aalto is now compatible with Soundplane version 1.0 and higher.
Fix mousewheel direction on Mac OS 10.7 and higher.
Accelerated drawing to the screen on Mac OS with OpenGL.
Optimized drawing scheduling to avoid glitches, especially in Logic.
User and factory presets now share the same location.
Improved ergonomics of patcher with larger handles and smoother graphics.
Fixed a drawing problem with bipolar dials.
Improved drag ergonomics for dials.
Kaivo is coming soon.
A quick rundown in case you haven’t heard: Kaivo is a software synthesizer that combines granular synthesis with physical modeling. Physical modeling is a way of making sounds using equations that model vibrating objects in real time, capable of generating sounds with an amazing liveliness, but often in forms that are difficult to control. Kaivo brings some of the latest academic research in this area to a very usable, patchable package. It wraps up two distinct kinds of synthesis that make surprising new sounds together. It’s going to be a great machine for new flavors of percussion and for making involving pads and textures like nothing else out there.
The Madrona Labs users group on Soundcloud has been very active this month with Kaivo tests as well as some nice new Aalto-related sounds and songs. Kaivo is in late beta (now closed as we sprint to the finish) and on track to release within a few weeks. I will announce a release date and price very soon.
Soundplane News
Soundplane owners: the 1.5.0 release of Aalto now works properly with the updated t3d format used in the Soundplane client 1.0. So you can now use Aalto with all of the new 1.0 zone features.
The Madrona Labs shop has a new layer of insulation on it, and as the days get longer I'm looking forward to getting back in there to work with some wood again. Very soon after Kaivo comes out, I will take orders for the next run of instruments. So the Soundplane run 3 schedule is now looking like: early March ordering, followed by late spring / early summer delivery. If you have any Soundplane questions in the meantime, please shoot me an email!
