E-MU ESI-32 for Pure Lofi Sampler Bliss [Demo]

Today I'm exploiting the ESI-32 rack sampler for lofi/crunchy/funky sound in multi-timbral mode. Drums were sampled at mono 22K then downsampled to 12K bandwidth, everything else down to 8K. All you're hearing is the ESI-32 sampler including built-in chorus, and internal LFO applied to autopan/vibrato. The audio was recorded direct to Tascam DR-05, no additional effects or mastering.

ESI-32: bit of an underdog, in that early 90s era when samplers started to overcome their limitations of memory, bandwidth, storage media, and processing capabilities. At a fraction of the current selling price for other vintage samplers of the late 80s that preceded it.

Roland JX-08 Synth Demo | 3 Vignettes in 3 Minutes

Ah the Roland JX-08 Boutique Synth module.
Sold my JX-8P some time ago and was pining for some of that vibe.
The JX-08 does very well, and a fraction of the studio space :D
Making use of the on-board sequencer and/or Keystep Pro.
Patches are derivations of factory presets.
Recorded direct, only the onboard effects are used.
No other mastering or effects have been added.

2xVCA Exploration of Audio Rates Amplitude Modulation

Want to spice up your ordinary analog VCOs?
In my previous VCA Tips and Tricks video I showed you how to do audio rate modulation using a VCA. It's basically a tremolo, only the control signal is another audio signal.
The result ends up sounding similar to ring mod or FM.
Today I'll show you exactly how to patch it up. And explore the cornucopia of interesting AM sounds using various input and control signals possible using a VCA.

104HP Eurorack Case Build From Cigar Boxes Timelapse

Today a timelapse build: a 104HP Eurorack case from cigar boxes. These are nice Spanish cedar cabinets, not cardboard. First I build a suitable box, install rack rails. Then solder together a bus board and install power supply. Last, putting all the modules inside.

Power Supply | Tiptop uZeus
Bus Board | Synthrotek Noise Filtering Distro
Rails + Nut Strip | Synthrotek 3mm
Screws | After Later 3mm

T2K-VCF Transcendent 2000 Eurorack Filter Adaptation Demo No Talking

T2K-VCF is a Eurorack modular adaptation of the Powertran Transcendent 2000 analog filter. Wavefolded material sounds phenomenal on this, coming from Capt'n Big-O. Op Amp gain compensation means no loss of bass frequencies even at extreme resonance settings. Resonance will self-oscillate and produces a nice aggressive sinewave alone. With some coaxing you can track the self-osc w/ v/oct. At the end you'll hear the filter output going into a phaser and delay.

Sound sources | Capt'n Big-O + GSE 101-VCO
Envelope | GSE 2xADSR
Phaser | GSE Polychrome Phaser
Delay | FX Aid
Recorded direct, no other mastering or effects.

T2K-VCF Eurorack Filter Adaptation Now Available [Powertran Transcendent 2000]

Introducing the T2K-VCF: an 8HP analog circuit adaptation of the lowpass/bandpass filter from an obscure 70s monosynth – Powertran Transcendent 2000. T2K-VCF is a 2-pole CA3080 OTA design w/ CA3140 op amp compensation at each stage. Translation = no loss of bass frequencies even at extreme resonance settings. Resonance will self-oscillate and produces a nice sinewave alone. T2K-VCF will fatten up routine oscillators - transform boring square/pulse and straight ramps into curvy vixens dressed to kill. Wavefolded material sounds phenomenal on this.

FREQUENCY | the initial Cutoff Frequency of the filter
RESONANCE | the depth of the peak frequency resonant feedback
IN1 & IN2 | Mix together 2 different audio signals, each w/ their own mix pot.
KB | Modulate the Cutoff Frequency w/ a V/oct signal or any other polar/bi-polar mod. Self-oscillation resonance will track v/oct loosely, but you will need to tweak the Initial Cutoff Frequency (Tune) and the KB amount knob (width tracking) to get there.
CV | Another Frequency mod can go here, range is greater than the KB input.
SHAPE | Select between LP lowpass or BP bandpass filter output w/ this mode switch.
OUT | the audio output jack of the filter

Specs 8HP Module width
24 mm Module depth
14 mA on +12V
25 mA on -12V
0ma on 5V (not used)

Can I Revive Kenwood DX-7030 DAT Machine Recorder?

Today I'm investigating issues with a Kenwood DX-7030 DAT Recorder.
The door opens and closes, but doesn't play the tape.
There's not a lot of mech service video content on this model.
And I have no service manual.
Can I get this thing working?

This is just a summary of about 10 hours of inspection, fiddling, proding, and poking.
Not including watching a load of DAT mech cleaning content.
Big shout out to 12voltvids
There you can see more detailed tips for cleaning DAT mechanisms.

Granular Synthesis - Pulse Synthesizers Load Runner Module Demo

Today I am checking out the Load Runner Granular Synthesizer Module by Pulse Synthesizers.
Back in 2018, Youtube user John Crombie was uploading these prototype videos of a sampler in development.
It started out life as a 4-channel sampler
And evolved into the granular processor we now know
How does it differ from Mutable Clouds, Akai S612, and Erica Sample Drum?
Let's take it for a spin and see how it sounds.

Recorded direct, no other mastering or effects.
