New High Density Modules From Grove Audio

via Grove Audio

"Several new modules combining dual and quad functions in one module will allow 2 complete full function 5U voices in only 8MU of panel space.

The update GMS-742a MIDI to CV Converter offers up to four channels of 16 bit CV outputs and 4 gate outputs. The module can produce up to 4 polyphonic control outputs.

The GMS-302 Dual VCO combines two VCOs with a 4 simultaneous waveform outputs and a selectable WAVE output that is chosen from one of five possible waveforms. The VCO has internal adjustments that allow the octaves to be calibrated accurately. The WAVE output also feeds an internal VCA, the control input of which is available on the panel. This allows amplitude control with an external CV without additional modules.

The GMS-709A Dual DADSR generates ADSR envelopes with an optional starting delay. The range of timing for the attach, decay and release is one millisecond to 10 seconds. The amplitude range of the ADSR waveform is 0 to 5V either plus or minus polarity, linear or exponential, and single shot, looping or gated operation.

The GMS-204 Dual Multimode Filter allows the user to select from one of 16 possible filter configurations with 1 to four poles and including low pass, bandpass, high pass, and all pass (phasor). Each filter has a voltage controlled resonance control and two exponential voltage controlled frequency inputs, 1V/Oct and adjustable.

The GMS-714 Ouad VCA has four high quality voltage controlled amplifiers that can be set for either logarithmic or linear control response. Each control input has an attenuverter that allows positive or negative control voltages. In addition, pairs of amplifier channels can be combined for a panning function. There is an internal 4 channel mono or two channel stereo mixer."

New Grove Audio WS-104 FM Operator aka the FM Ogre & GMS-1340 Polywav™ In the Works

via Grove Audio (no pics):

"FM Operator, WAV Player, VCO In Prototype

There is progress on the FM Ogre, officially the WS-104 FM Operator. The EU version prototype is up and running. Boards are in progress for the MU version which has some sub--assemblies. Hopefully, a demo and pictures of the panels will be up soon.

The GMS-1340 Polywav™ Player WAV sample player module prototype is coming together. This module will play back up to 14 16 bit 44.1 KHz stereo WAV files simultaneously, each with independent volume level under trigger or MIDI control. The first version for MU will use a 2MU panel. 16 1/4 inch jacks will allow gate triggers to start predefined sample playback. Two sets of CV and trigger inputs will allow voltage controlled initiation of sample playback from the current selected sample library. This will allow a group of samples representing a scale such as the Mellotron three violin sample set to be played from a CV source.

There is a MIDI DIN input that will accept note and control commands from a controller device to play sample sets. A separate sample set can be assigned to each of 16 MIDI channels. MIDI bank select commands can change the assigned sample bank for each channel.

A front panel OLED display and encoder will allow setting sample sets, MIDI channels, trigger assignments and other parameters. The SDHC card reader, accessible through the front panel will accept a card with up to 32GB of WAV samples. The user will then be able to select from a pool of 2048 samples to combine these into sample sets. Samples need to be recorded as 16 bit 44.1 KHz stereo WAV recordings. The sample length is not limited.

The GMS-321b Voltage Controlled Oscillator module is coming along. I have located a source for one of the last remaining NOS parts needed to build up the module. This is a recreation of the Moog 921b VCO and will be available as a 1MU module."

A Nutting They Did Go

"A bit of a zany tribute to NASA and other space exploration organizations around the world and also to science fiction writers and producers. They both inspire each other and provide the rest of us with some of our most exciting hopes, dreams and fantasies.

Thanks for watching, liking and commenting on my videos!

DETAILS:

Main Bass Line: 3 x Synth Tech MOTM-300 VCO's, sub-mixed with a Moon Modular M526 mixer and then into a Grove Audio PM Resonator followed by a prototype/beta sample of Grove Audio's G294A low pass filter kit I built (basically a Moog 904A clone) and finally into a MOTM-190 VCA that is being modulated by a Moon M511C VC EG. A Moon M569 sequencer provides 1 row of pitch control for the VCOs and gates for the EG, 2 rows of CV for the EG and the 4th row is transposing rows 1 and 2 via my custom modification. A MOTM-380 quad LFO also modulates the overall CV level of the EG. Strymon Mobius and BigSky pedals provided effects processing.

Occasional Melodic Line: Novation UltraNova MIDI'd to a Korg microStation playing preset patches in unison.

Rhythm Line: Roland TR505 drum machine playing stock patterns. MIDI out of the TR505 also goes to a Moon Modular M553 MIDI-To-Clock module to drive the M569 sequencer.

Lift Off Roar: Just a quick bit of sound design I did with the 5U modular. Two outputs from a MOTM-101 Noise module go into a Happy Nerding Fun VCF with a little help from a Synthesizers.com Q125 Signal processor etc.

Asteroid Thump And Following Explosion: these are licensed from Pond5.com and I had used them in a previous video a couple years ago.

Movie Dialog Clips: There are all licensed from Loopmasters.com and from two different movies; Assignment Outer Space and Cosmic Mission. (except for the word 'DERP' that I recorded myself ;-)

Video Clips: A majority of the clips are public domain and I downloaded them for free from www.pond5.com! Such a great resource for video makes, check 'em out! Some of the clips I had licensed before and used in prior videos.

Modular synth audio was recorded to a Marantz PMD-661 flash recorder and then transferred to my PC. Keyboard synths were recorded direct to the PC via the Ultranova's USB interface. My 'Derp Voice' was recorded direct to the PC using a Blue Microphones Yeti USB mic.

Everything was mixed/assembled in Sony Movie Studio Platinum 12."

Grove Audio USB Host Extender Module Prototype

via Grove Audio

"The USB Host Extender Module, GMS-632X is undergoing testing including the USB host capability and running Arduino sketches. The USB library is accessible from within an Arduino sketch and uses interrupts so the device detect, attach and eject functions continue to operate in the background while user code executes in the foreground.

Here [left] the extender module is mounted next to the GMS-632 USB/MIDI/CV Interface module. The two are connected by a short ribbon cable with IDC10 connectors. The extender module does not require a power connector. The extender module can be used with either the GMS-632 or the GMS-634 modules.

Here [below] the module is being used to host an m-Audio Keystation 49. Through the GMS-632 module, keypresses are converted into pairs of CV and gate signals. The GMS-632 is simultaneously connected to a laptop computer as a USB device, through which it can receive USB MIDI or program uploads.

"The GMS-634EU Programmable Processor has a Teensy 3.1 processor board with a 32 bit ARM Cortex-M4 processor, USB interface, 96MHz clock, 512K of program memory and 65K of data memory. The supporting module includes two analog inputs with attenuators, two extra potentiometer-controlled voltage sources, 2 analog outputs supported by a two channel 12 bit DAC, two gate level inputs, two gate level outputs, a two channel in and out audio interface with a 24 bit 96 KHz sample rate CODEC, a standard 5 pin DIN MIDI input and output, and a 3.5mm stereo headphone output with level control.

By using the Arduino IDE with the Teensyduino add-in users of this module can download their own sketches to the module to utilize the processing power and substantially larger program space contained in this processor. A number of modular synthesizer specific sketches are available and can be downloaded and run in this module using the Teensy support libraries and some minor code modifications. In addition, libraries are provided to allow users to access the provided stereo CODEC as a high quality stereo audio input and output. The input and output jacks support -10dB line level signals.

The module can be purchased assembled or in kit form. The kit includes a Teensy 3.1 processor with pre-installed headers. The surface mount header that is used to access more of the processor I/O is also pre-installed. The CODEC board is supplied with pre-installed headers, too. The CODEC board has a socket for a mini-SD card, accessible from the rear of the module, and has been configured with SD card libraries in the Arduino environment."

Grove Audio GMS709a Dual DADSR Envelope Generator with Multiple Modes

"The GMS709a dual DADSR envelope generator, in addition to the normal ADSR controls adds a delay setting prior to the start of the envelope. The delay time interval can range from 1 millisecond to 10 seconds. Other panel controls can select an exponential envelope or a linear envelope with either positive or negative direction. The operating modes are Normal, Gated and Loop. In Loop mode, by adjusting the delay, attack and decay controls, the envelope generator will generate a series of envelopes with varying frequency.

The gate input connector also includes a trigger input on the ring connection so that a trigger source can restart the Attack/Decay phase of the envelope while the gate signal remains active. There is also a front panel gate pushbutton to trigger the envelope for each channel."

Grove Audio Eurorack USB MIDI to CV Converter

"A Eurorack compatible USB MIDI to CV converter uses the Teensy 3.1 microcontroller as its USB port and controller. The 6HP wide unit includes 2 CV channels, 2 gate channels, an isolated DIN MIDI input connector and a DIN MIDI output connector.

The control voltage output range is internally settable to 0-10 Volts or -5-+5 Volts. The gate signal is 0-5 Volts active-high. The software for the unit is open-source and can be reloaded and modified by the user. A programming development environment that utilizes the Arduino IDE with a Teensy support add-in can be used to create new functions using Arduino-like commands.

The module will be available in the Synth Store either assembled or as a complete kit. A demo program will be available that provides a two CV output and also allows USB MIDI note commands to be sent and received from the serial MIDI ports."

"This my first attempt at a (semi) live modular performance (I added some drums part of the way through). First take on the modular, and first take on the drums. Kind of random. Since I normally multitrack everything, I just wanted to see if I could work this way.... The modular is driven by Numerology, routed through an MOTM-650 midi-cv converter. Modules are synthesizers.com, MegaOhm Audio, MOTM, SSL, and Grove Audio. Drums are Roland v-drums (TD-12)."

Kickback

Published on May 27, 2013 davidryle·111 videos

"Real time modular synthesizer performance.
A Synthesizers.com Q960, Q119 and an STG Soundlabs VMS were used along with the Moon 563 Trigger Sequencer and the Moon 554 Octal Clock Divider for time based pitch and gate work.
The main bass line sequence was from the Q960 (which was the master clock) & divided up between three Q106 VCO's. I used the Q963 Trigger Bus to send portions of the sequence to the various vco's. A third vco was ping'd on beat six for the upper midrange note. The downbeat was doubled and a sub oscillator added for punch.
The pulsating string-like sound was the Q119 sequencer into an Synthetic Sound Labs 1200 VCO. It was tuned using the CV IN jack instead of the 1V/OCT. This allowed me to fine tune the half scale for a more analog sound pitch sequence. The Moon 563 was providing most of the off-beat timings and the Q119 was the main pulse timing. A Q962 Sequential Switch was used to divide the pulse string sound into three separate gate timings to the EG.
The high pitched scrape sound which came and went with a pulse core was the SST/Ian Fritz DDVCO through a Grove Audio PM Resonator module and on to a VCA which used a Mega Ohm Audio LFO2 to handle the intermittent sweep in and out. The DDVCO had a MIX CV from another LFO2 and octave switching with a S&H square wave.
The squelchy percussive filter sweep noise was the Q107 State Variable Filter in resonant peak overdrive mode. The Sputnik VCS module provided the timing to the filter and I got to play this by hand throughout. A Q127 FFB was employed to tame the sound.
The final sweeping and pulsing background sound was the STG VMS sent to a pair of Q106 vco's in soft sync. The carrier was pitch modulated by the voltage from the VMS. The sound was sent through a Polivoks LPFilter and finalized through a Blue Sky plate reverb.
A Lexicon MX200, TC Electronic D-Two and a pair of Behringer DD400's filled out the delay lineup."

FutureRetro Mobius Sequencer Test

Published on Feb 19, 2013 JohnLRice·189 videos

"This quickly recorded demo of my FutureRetro Mobius sequencer is post-sale and pre-shipment. I can't remember if I had ever really tried this after I purchased it used years ago. I know I powered it up at least. I should have kept it but, oh well. The existing sequences I'm playing with were most likely programmed by the previous owner.

The patch it is controlling is two Synth Tech MOTM-300 VCOs Pulse out with MOTM-380LFO for PWM, a MOTM-440 VCF, MOTM-800EG and MOTM-190 VCA into a Roland M-120 line mixer. One effects send of the mixer goes out to a Modcan 59B delay then to a Grove Audio PM Resonator and then to a COTK C1660 Phase Processor before returning. The other effect loop goes to a Roland RSP-550 effect unit set to a Hall reverb."

Grove Audio GMS-294A VC Low Pass Filter 4 Pole Transistor Ladder Filter

via Grove Audio

"The GMS-294A VC Low Pass Filter is an accurate recreation of the Robert Moog-designed 4 pole transistor ladder filter. As much as possible, all original parts and matched pairs of 2n3392 transistors were used in the construction of the unit.

The module is implemented in a 1MU panel width and includes a complement of the original controls with the addition of a gain control on the CV in and a gain control for the audio input to the filter. An additional CV input is scaled for 1V/OCT. When the resonance control is turned up to near maximum, the filter will become a voltage controlled sine wave oscillator."
