This is a quick follow up to the last Ensoniq EPS 16+ Sampler demo. In my previous EPS 16 Plus demo it was suggested I use a phaser to help give the sound some movement. After all it worked for Jean Michel Jarre on his Eminent. I'm in luck! I happen to have a Boss PH-2 Super Phaser. I also use my delay trick from my previous PH-2 demo to help widen the stereo image a bit.

In this video I am running various synthesizers through a Boss/Roland PH-2 Super Phaser Pedal. The PH-2 is an analog pedal made from the mid 80's to 2001. Since the PH-2 is monophonic I will be auditioning it in both mono, and with stereo widening provided by an Eventide Timefactor. Sounds range from Jean Michel Jarre to Polymoog Vox Humana as heard on Gary Numan 'Cars'.

In this video I am showing what the DRE4MTR4CK sequencer module does best: dealing with fast incoming clock signals. With the DRE4MTR4CK I change octaves and patterns for each part, and rotate the track data.
Track 1: Synthesizer Box
Track 2: DNA Symbiotic Waves going to the JP-6 VCF
Track 3: Disting Osc going to Doepfer SEM filter
Tracks 1-3 going to Deflector Shield Phase Shifter and Big Sky
Clock randomization by 4MS RCD, getting its data rotated by Pittsburgh Toolbox S/H.
Track 4: Bass Pads by Juno-1 played off-camera (right hand), my own patch called Aurora Pad 2.

Today I am messing around with a vintage Ensoniq EPS 16 Plus sampler. These were made around 1990 (27 years ago!) and are an excellent crunchy sampler alternative to Akai S-900 and E-mu Emulator. For this video I sampled an ARP Solina String Ensemble. This is less of a tutorial and more of a comparison. Does the sampler do the Solina any justice? Check it out and see. Be sure to click 'LIKE' and thanks for watching.

In this video I show what I did to resolve my power supply issues on the Oberheim Matrix-12 analog synthesizer. Symptoms were intermittent non-boot, locking up, and the dreaded Voice 1 Processor Malfunction message. Along the way I'll talk about how the power supply works and how it is different than many synths from the era prior to this. Even though the Oberheim Xpander is a little different than the Matrix-12, its power supply works exactly the same. This may not enable you to fix your Matrix-12/Xpander completely, nor answer ALL questions you may have...but hopefully it will be helpful information.
YOU ASSUME ALL RISK WHEN REPAIRING YOUR OWN ELECTRONIC INSTRUMENTS! There's no shame in asking a friend for help or taking it to a reputable synthesizer technician. BE SURE TO UNPLUG THE SYNTH PRIOR TO DOING THIS KIND OF WORK.

sorry I don't have capacitor numbers, I did that work 2 years ago

The Oberheim Matrix-12 was cooperating today, so I thought I better make a video before something happens again. Using some reverb and delay, recorded direct and no audio post processing.

Rolling out some new patches for the Juno-1/2 available on my download post for this blog. A full bank of patches including the sounds from Demo #1. In this video I have selected a few of my personal favorites: bass, arpeggios, and soundscapes/pads. There are copious amounts of Big Sky reverb, a couple of sounds use the Timefactor delay. Basses don't usually need anything. Sounds were programmed using the indispensable Stereoping synth controller, also used briefly in this demo. Recorded direct through a Mackie 802-VLZ mixer to a Tascam DR-05.

Designing a module such as this has its challenges. Things happen when you are designing a module on your own, and building it with your own two hands. Just last week I thought the project was dead in the water. But I persevered once more. I have risked everything, all my cards are on the table. The DRE4MTR4CK has been my labor of love for over 2 months in the making. With hard work, persistence, and steady dedication the DRE4MTR4CK is now a reality. An organic melody progression sequencer, with polyrhythmic capability.
Performance using evolving chord changes with my custom DRE4MTR4CK Euro module. It has 4 independent tracks of polyphonic pitch control:
Track 1: Pittsburgh Synth Box, internal filter
Track 2: DNA Symbiotic Waves, JP-6 Filter clone
Track 3: Disting MK3, Doepfer SEM filter
Track 4: Rings, no filter.
Clocking direct to envelopes, triggering pitch changes manually. Track 1 pitch CV is going through a PM Toolbox slew limiter. Mix is going to Timefactor delay. Recorded direct through a Mackie 802 to a Tascam DR-05.

The DRE4MTR4CK is a simple and intuitive Pitch CV sequencer. It has 4 steps, and it has 4 Individual tracks. Each track has its own clock input, clock output, and Pitch CV output. In this way, it can behave like 4 completely independent sequencers.
In this video I show how to use the DRE4MTR4CK in more detail.
1:23 Installation Options
Correction: the graphics say -5v when it should say +5v (positive 5v).

3:32 Connections and Operations
DRE4MTR4CK is a custom module built by hand. Full specs available on my previous post.
