"The Dual Delay represents the next step in delay based effects from Modcan. We took the existing Digital Delay 59 from the A/B series and dramatically reworked both the hardware and firmware model to add significant features and enhancements in the conversion to Euro format.

The most obviously apparent change was to make it a Dual with independant controls for each channel. We also added selectable modes for delay type. Choices are Re-sampling (pitch shifting effect when altering delay time) and a "Clean" mode for standard Digital Delay effects without pitch shifting.

Low noise design using 48kHz sample rate, 32bit DSP processing and 16bit I/O.

Other features include 0Hz-21K continuously variable 4 Pole Lowpass filter in the delay feedback path for "Analog BBD/Tape Delay" emulation. The filter has full range self oscillating resonance with voltage control of resonance amount and filter cutoff.

Input signals can be routed as two mono delays or stereo or as a dual Tap delay with delays in series internally. Each channel can be either in clean or resample modes and can also be patched in series and parallel for external feedback path. Delay time can be set by panel control knob, CV, external sync pulse and tap tempo buttons. Also sync division is available to divide the pulse clock. Each delay has 3 ranges

Resample Delay Ranges
Lo: 0.01s - 0.06s
Mid: 0.06s - 0.5s
Hi: 0.5s - 4s

Clean Delay Ranges
Lo: 0.0006 - 0.02s
Mid: 0.02s - 0.91s
Hi: 0.91s - 5.46s

All the functions (except input level) that are controlled by panel knobs have matching CV inputs allowing for a wide range of flexible control modulation. The module uses very low current requiring only 40mA for operation and will work with any power supply between 8 and 15V. Less current than many simple analogue modules.

Two independant mono delays
48kHz sample rate, 32bit DSP processing and 16bit I/O

"This is a version of Modcan VCDO 58B. The VCDO 58B represents a new breed of sound generation for the modular environment. The primary design goal was to implement a variety of digital synthesis techniques and to combine them together in one module.

The most significant wave-shaping feature of the 58B utilizes the technique referred to as Two-Operator FM, providing a wide variety of timbres from mellow bell like tones to complex distortion.

The inclusion of harmonically rich sample based wave tables extends the complexity of the FM effect comparable to multi-operator systems.
AM (Amplitude Modulation) is also available on-board as is standard Exponential FM using the Expo FM Jack.

Conventional analogue VCOs are modulated with externally generated signals from LFOs and secondary VCOs etc.
Digital implementation of the VCDO 58B affords superior FM stability with internally generated, phase locked, sine table modulator.
The FM Index function controls the amplitude or depth of the modulation while the Ratio control tunes the modulator to a
rational frequency value relative to the carrier frequency.
Phase locking the modulator with the carrier produces beat-free timbres that retain spectral relationships over the entire frequency range.

The 58B includes standard VCO wave forms and adds several sample based wave tables. Pulse width modulation and hard sync are also supported.
Switch selectable quantized pitch tracking in semi-tone steps or non-quantized continuous frequency control with fine tune.
Firmware by DSP designer Eric Brombaugh.

Features

32-bit NCO - 50 micro-Hertz resolution (no zippering)
Phase-locked FM/PM gives beat-free modulation
32 real-time voltage controlled modulation/carrier ratios
Fractional modulation/carrier ratios for complex sub-harmonics
Modulation index range from 0 to 314% for a wide range of continuously varying wave shapes.
Real-time voltage-controlled modulation index for subtle wave shaping
32-bit pseudo-random noise generator - won't repeat for 119
 hours at highest frequency setting; longer at lower frequencies.
Voltage controlled selection of 16 wave forms
Quadrature secondary output at 90 degrees out of phase
Amplitude and Pulse width Modulation AM/PWM
Switch selectable quantized 1V/Oct input
Audio and LFO range frequency
Voltage controlled FM Index and modulation Ratio
Crystal tuning stability with +/-0.005% pitch tracking accuracy over 18 octaves
Waves: Sine, Triangle, Saw, Square w/PWM, Double Pulse w/PWM, Random Stepped (with CV controlled variable interpolation), 10 sample based wave tables"

"The MS-10 is a cool & classic analog synth known for its great bass and percussive sounds. It was released by Korg in 1978 as an entry-level, simple monophonic single-VCO analog synthesizer. With the authentic look of a mini-modular its single VCO is patchable using standard 1/4 inch patch cords to the VCF and VCA. It really is a powerful little mono-synth with plenty of knobs and a compact 32-note keyboard. It is CV/Gate controllable. A very cool feature is its external input to filter which allows you to filter external sound sources!.."

"FROM THE STUDIO OF EARTH EMPIRE (SYNTH-POP / INDUSTRIAL / TECHNO ARTISTS)
reverbnation/earthempire

DAVE SMITH PROPHET 08 PE EDITION 8-VOICE ANALOG SYNTHESIZER
WORKS & SOUNDS GREAT! HAS SOME COSMETIC THINGS TO MENTION-
MISSING LEFT-FRONT FOOT, SMALL GAP BETWEEN KEYS, MISSING ONE SCREW
ON RIGHT FRONT FACE COVERED WITH BLACK ELECTRICAL TAPE. IT HAS SOME SMALL
SCRATCHES & DINGS ON THE FACE & SOME KNICKS ON THE WOOD SIDE PANELS.
IT HAS SOME WORN & SLIGHTLY BENT KNOBS THAT DON'T ROTATE ON THE KNOB POST PERFECTLY
STRAIGHT BUT DO TURN CLEAN & DO NOT EFFECT THE PERFORMANCE OF THE SYNTHESIZER.
THERE ARE DINGS & SCRATCHES ON THE TOPS OF THE KNOBS & LIGHT SCRATCHES AROUND THE FACE.
IF YOU NEED THE POWER & SOUND OF A PROPHET 08 PE & DON'T MIND A FEW DINGS & SCRATCHES
AT A LOW PRICE THEN THIS SYNTH IS FOR YOU!! I THINK REPLACING THE KNOBS WILL MAKE
A BIG DIFFERENCE ON HOW SHE LOOKS! I SEE THEM HERE ON EBAY ALL THE TIME!
8.9 OUT OF 10 IN LOOKS! GET IT BEFORE IT GETS AWAY!!!

COMES WITH ORIGINAL POWER SUPPLY!!!"

Moog MicroMoog Analog Synthesizer! Clasic synth from the mid-to-late '70's in FANTASTIC
Condition!!! (Just see the pics!!) Everything works! Sounds ANALOG & PHAT!!!!
Pitch Ribbon works great but need to apply stronger pressure compared to my Kronos
Ribbon controller. 1 key (see pic 3) plays great but needs it's contact cleaned.
Holding it down for a bit SOMETIMES it cuts in & out. Otherwise it is a near perfect
MicroMoog specimen! I use it for long drones, bass, sweeps & S&H modulation!
Run this thru good effects & you are a MOOG ANALOG GOD!..."
