04:10 Outro

Here's the full recap of the video in case anything is unclear when it comes to composing with the Elektron Octatrack and Analog Four together,

Both of these setups presume that the Octatrack and Analog Four are connected with a 5-Pin DIN MIDI cable: Going from the MIDI OUT of the Octatrack to the MIDI IN of the Analog Four.

You have two choices:
Option 1 - Octatrack is the leader and Analog Four follows
You must have Prog. Change enabled in the Project Settings of the Octatrack (Press Func. + Mixer to access).
This is a checkbox within the MIDI category (the last option in the pop up menu) in the Sync settings. You also need to set a MIDI channel number (that isn't being used for anything else) to transmit those program changes (aka. Pattern Changes) to the Analog Four. Use the arrows and the level knob to set that. Before moving to the Analog Four, check that TRANSP and CLOCK Send boxes are checked.
Over on the the Analog Four, press Function + Global (the last key in the mini keyboard on the unit) to access the synth's settings. Arrow down through the options until you reach the MIDI Config item. Hit "Yes".
Check the Sync Settings, Clock Receive and Transport Receive should both be checked.
Then Arrow down to the "Channels" menu item. Press "Yes". Arrow down to the 9th menu item "PROG CH IN CH" and make sure the channel number matches the sending channel from the Octatrack. Use Knob A to change, if necessary.
Ensure that Song Mode is not on for the Analog Four. Now the Analog Four will play whatever pattern the Octatrack is playing at the time.

Option 2 - There are no leaders Octatrack sets the tempo and play/stop.
To make this happen, follow the instructions above but you need to ensure that on the Octatrack PROG CH is unchecked or off. This is way it isn't sending marching orders to the Analog Four. Everything else should remain the same.

Cre8audio East Beast Overlays by OVERSYNTH

"Whitephase" & "Blackphase" overlays for the Cre8Audio EastBeast.


"This is an aftermarket overlay that you place over the front panel faceplate of your Cre8audio East Beast synthesizer.

The overlay's artwork uses high contrast graphics and large fonts for easy viewing in low light.

To install the overlay, simply remove all the front panel knobs from your synthesizer, then remove the backing from the included adhesive tabs on the underside of the overlay. Place the overlay over your synthesizer and press down to make sure the adhesive is holding. The adhesive is low-tack to allow for easy removel. Next, re-install all of the knobs.

The overlay is printed on a highly durable, waterproof, and 100% recyclable polyester sheet (not vinyl, fiber, or plant-based). The matte finish is designed to minimize reflections from ambient light for maximum readability.

If the overlay becomes dirty, we recommend gently wiping it down with a soft cloth that is dry or slightly moistened with water. We do not recommend cleaning the overlay with isopropyl alcohol as this may damage the artwork. Based on our testing, the following substances will severely damage the artwork if left on the surface for an extended period of time: tea tree oil, acetone, nail polish remover, bleach, household cleaners, and hand sanitizer.

Our products are custom manufactured in small batches based on customer demand.

This product is made in the USA and ships from Portland, Oregon. International customers are responsible for paying all import duty and custom clearance fees for their country.

This is an aftermarket product. The product includes the overlay only and does not include a Cre8audio East Beast synthesizer. Oversynth is in no way affiliated with Cre8audio."

The FDR Drive - a ride along the eastern edge of Manhattan with original music

"A ride along the eastern edge of Manhattan via the FDR Drive. We start at Third Avenue in the Bronx, cross the Third Avenue Bridge into Manhattan and merge onto the Harlem River Drive. At the RFK (Triboro) Bridge, the Harlem River Drive becomes the FDR Drive, which we follow to lower Manhattan until the Brooklyn Bridge. Along the way, we observe the skyline on either side of the East River, and pass several notable landmarks.

G-Sonique Psytrance AI Voices - VST / AU plug-in instrument for Win & Mac - psytrance intro voices

video upload by G-Sonique

"G-Sonique Psytrance AI Voices - VST / AU plug-in instrument for Win & Mac - psytrance intro voices Available here:

Psytrance music is characterized by exciting and elaborate intros, outros, intermezzos, breakouts. Nothing gets a crowd crazy more than an professional built-up graduating from chill intermezzo to a dance passage with atomic bomb energy.

And it is in these passages often interesting thematic voices /vocalsare used. However, it seems boring to people if they hear the same message 1000 times from Timothy Leary, McKenna or from the movie Fear and Loathing in Las Vegas. People want to hear something new, different. That's why the Psytrance A.I. Voices - VST / AU plug-in instrument for Win and Mac was created. AI voices instrument is full of robotic, synthetic psytrance themed psychedelic voices and slogans. The sounds are created by artificial intelligence, then resampled and resynthesized with various futuristic sound design methods. They sound excellent in a wide range of octaves. You will find every voice in different sound variations from classic AIs, to robotic, mystical, crystal-glass-sounding ethereal beings, matrix entities and witches, created deep in the mind of artificial intelligence.

These notes can be used in intros/interludes as well as together with beats.

Listen to the demo. Spice up your production with unexpected sounds - people remember the spoken word best because it is closest to our DNA.

Very well usable in genres such as: psytrance, hitech, darkpsy, full-on psytrance, progressive, darkprog, tech trance, psycore, experimental, neurofunk, psybient, but also techno, minimal and others.

FH-2 Arpeggiator tips #1 - The 'Arp Reset' setting

video upload by Expert Sleepers

SH 01 Gaia Live Improv/Demo - no talking

video upload by O.Z. Hall

"The Roland Gaia virtual analog (VA) synthesizer is really quite impressive (IMHO). It features VA architecture with many filter formats as well as effects. Although it is a "single oscillator" synth, there are three complete VA layers, including oscillator sync between layers!
There are also 8 good sampled presets, when you want sampled piano, strings, voices, etc.
Add to all that a General Midi digital sound module (accessible only via MIDI). Per the GM standard, MIDI channel 10 lets you access a good sounding drum kit. This is the kit I'm using in the video.
The drums are triggered vial MIDI from the Arturia Beatstep Pro sequencer.
The synth preset used is original. The 'Phrase Recorder' sequences are original. Of course, the improvisational playing and parameter adjustments are live. I hope listening is as fun for you as playing was for me!"

Sci-Fi Sound FX DSI Poly Evolver Pads

video upload by MIDERA

"You may be wondering why all the knobs are missing on my Poly Evolver. Well, I ripped them off so that I could see what they looked like on my Roland System 8. They looked ok. But the problem with the System 8 really isn't in the knobs, but in the poor keybed (which I even opened up and lubed and it still doesn't feel nice). Well, I decided to keep them off and I think I'm going to upgrade my encoders to the 24-detented versions. That will be a lot of work if I do it.

Anyway, I am sitting with the Poly Evolver and wondering whether it's something I should keep, being only 4 voices. That frustrates me quite a bit actually. I feel like at 6 voices it would have been amazing, and, I suppose it is only at 4 voices, but I find 6 is really the sweet spot. It's such a great synth though. I do have a mono evolver to add a voice, but it has a bug whereby the two won't always sound identical. Plus, you can't use the Audio inputs on the Poly Evolver to take the extra voice of the Mono Evolver. Just don't know what DSI was thinking. Only the PE Rack has that combination. Missed opportunity.

Well, I guess as I played the Poly Evolver, I realized just how crazy this thing gets. I don't know any other synths that really get this crazy. I don't think any that I have really do this sequencing like that. Maybe the Korg Radias, but it doesn't really sound as nice (and doesn't have analog voices and filters).

So - what you have is me going through and just messing around with a patch I made. I started it mid-way through my journey. I added the beginning portion to the end so you're welcome to get there if you want - although I find that people only watch the first few minutes of my videos anyway, so I doubt anyone will even get to that part!

Used Eventide Blackhole VST for reverb."
