Astro + Arturia = AWESOME!

video upload by Jeremy Parker

"My love of astrophotography has intersected with my love of synthesizers in a beautiful venn diagram of awesomeness. At least I'm hoping so! One of the reasons I purchased my Arturia POLYBRUTE was exactly for making space music. It's been over a year since my last astrophotograhy video, so it's about that time.

Most of the images were taken from darker skies, but a couple came from home under my light pollution with the new astro camera and filters. I listed some details on the sounds I used, and also the images you'll see. If you want more dorky details, see below:

Scope: StellarVue SV102T, MoonLite NiteCrawler
Mount: Explore Scientific PMC-Eight G11, Spring-loaded OPWB on DEC, O-Vision Worm on RA
Cameras: QHY600 & QHYCFW3-L w/Chroma LRGB & 3nm Ha/OIII/SII, Nikon D5300 H-alpha mod, Nikon Z6, GoPro Hero8 Black
Guiding & Alignment: StellarVue F50 GuideScope & ZWO ASI290MM Mini Guide Cam, QHY Polemaster
Computer & Software: Surface Pro Windows 10, ASCOM POTH, CdC, PHD2, SGP, Backyard Nikon

Arturia POLYBRUTE sounds used:
"Hawkins" (pad) - beginning and end astmospheric chords
"Chonky" (bass) - basslines in main song
"VHS Keys" (keys) - chords in main song
"Claire De Lune" (keys) - chords in chorus behind piano solo
"Deaths Harmonica" (lead) - melody in main song

Other sounds:
Addictive Drums VST - drums in main song
Yamaha S3X - acoustic piano in main song solo
Aether VST - reverb on piano

Mics on piano:
KSM141s in cardioid pair, ORTF (approx)
KSM44a cardioid over middle C"

Manis Iteritas from Noise Engineering-sound demo with modulation controls and voice-over

video upload by Rochefsky

"I was so blown away with the sound and modulation controls on the Manis Iteritas that I had to make a video to let other people hear how the bash, smash and profundity controls change the sound on a simple sequence. I don’t try to describe how the module works because it’s so new to me (I didn’t read enough of the manual when I made this video) so I just to describe what controls I’m changing and you can judge the sound yourself.

The Manis is in a larger 6U 104hp Eurorack modular kit with 20 other Noise Engineering modules, but none of the others are in the signal path of this demo.

The sequence is coming from an Artutia Keystep Pro.

The voice mic is a Shure SM58 direct to my mixer."

Gotharman's Urano: Patching Tutorial #TTNM


"Learn the different ways to patch Gotharman's Urano modules together. It's a pretty cool control scheme. The Urano is a unique and fun modular synthesizer in a box from Denmark, featuring real analog filters, lots of audio effects, free patchability and it's also a great companion to a Eurorack or other modular system.

Space Cadet: Sequential TAKE 5 - Prophet REV2 - Toraiz AS 1 & PEAK

video upload by Alba Ecstasy

"Ambient patches:
Here it is, the promised track, containing the Sequential TAKE 5, Prophet REV2 and Toraiz AS-1.
The Novation PEAK adds a bit of sensation with an FX patch (from the next sound bank I'm preparing).
Each one of the synths runs the sequences on their internal clock, with no MIDI connectivity between them or having a master clock.
All internal effects, just a bit of reverb on the REV 2 (Eventide Blackhole). Enjoy!"

Building a Drum Computer for the RetroChallenge 2021/11

video upload by Michael Wessel

This one is in via Michael Wessel.

"This is my entry for the RetroChallenge 2021/10.

My Hackaday project page explains some more details"

And via Hackaday:

"In this episode, I extend the pattern-based drum computer to full 16 steps / beats (4 bars x 4 beats), and tailor for real time drum pattern input (like a real drum computer).

This requires inputting data from the keypad using the KIN (Keyboard Input) op-code, whilst playing back the pattern, and hence isn't possible with the standard Microtronic KIN. Thus, I implemented a non-blocking KIN behavior. Utilizing 2 more vacuous op-codes, I can now toggle between the standard blocking KIN input behavior, and the new non-blocking behavior.

The op-codes for determining the KIN mode of operation are 3F0 (blocking KIN mode) and 3F1 (non-blocking KIN mode). By default, the Microtronic only uses blocking KIN. The vacuous op-codes 3F0 and 3F1 are idempotent immediate AND (ANDI) op-codes, i.e., the operand 0xF = 0b1111 = 15 is idempotent for 4bit registers, and hence, no (existing or new) program would ever use them. So it is safe to assign the mode toggling extra side-effect to them.

In general, the following vacuous op-codes are available for side effect extension:

MOV x,x: copy register x onto register x, 0xx
ADDI 0,x: add 0 to register x, 50x
SUBI 0,x: subtract 0 from register x, 70x
ANDI F,x: bitwise AND of register x with F, 3Fx"

Moog Sub37 Prophet Rev2 Volca Drum Stretchweaver beats vocals | live electronic burial style beats

video upload by Nate Connelly

"Moog Sub37 Prophet Rev Volca Drum Stretchweaver beats vocals live ambient electronic burial style beats and drums.

The mix you hear is as it was performed. No overdubs. The Sub37 and the Prophet Rev2 are going through the Strymon BigSky, and then into my computer via my GoldMike Pre-Amp. I applied a little multi-band compression and a limiter to the final stereo mix in post.

The track is titled 'Grey Lies' and is a work in progress.

The white noise you hear was sampled from the Sub37 and looped in the DAW. The bass tones are coming from the Moog Sub37 and into channel 1 of the stretch weaver - the melody loop sequence is coming from the Prophet Rev2 and into channel 2 of the stretchweaver. The stretchweaver is set to the tape setting, and as the bass opens up it controls the side-chain to the melody on the Prophet Rev2. The volca drum is playing the simple mid-kick pattern from the start, with some hi-hats coming in at the peak of the track. I created the burial style drum pattern in Cubase 11 Pro using various samples of rocks and stones, along with various kick drum layers. I took the vocal sample from an acapella on Youtube and re-arranged the pitch and the words to make my own melody and meaning.

00:00 - start
01:03 - intensity surge
01:56 - drums & vocals
03:55 - progression & intensity
05:14 - more-ness

Best Ambient Synth Shootout #116: Arturia MicroFreak - Song 2

video upload by Christian's Sonic Spaces

Song 1 here.

"This is the second (quite minimalistic) song with the MicroFreak. It's a monophonic/paraphonic synthesizer with a digital oscillator section containing 12 different algorithms and an analog filter.

I used for the recording the following FX chain: MicroFreak - Digitech Obscura - Pigtronix Echolution 2 Deluxe - GFI System Specular Reverb 2. Depending on the recorded track some FX are deactivated

The signal went through a Presonus StudioLive 16.0.2 into the PC via USB for recording. To create the complete song I recorded consecutively several stereo tracks. The final song was then mastered with a bit EQ and compression on some tracks and some limiting on the master track.

Well, I decided to go back to the basics, but at the same time make something useful for the synth community and do a kind of competition (I like competitions;-). What's my best synth for ambient music :-)"

Rare Novation MidiCon & BassStation Rack

via this auction

"the BassStation works flawlessly. there's a bit of wear on the bottom, and the ears are a bit bent, but this is an incredible machine that doesn't pop up so often stateside. very sturdy and quite the performer. the Midicon works well with an adapter, but I'm afraid not so much with batteries as the contacts need replacing. this super responsive MIDI controller can receive velocity data and feature 2 wheels. honestly I've never had much luck pairing it with the BassStation, but I do use it with my other synths, most notably with my Roland MC-909. the case is similar in format to the original BassStation and is made of plastic as well. doesn't feel all that sturdy, but the keys, wheels and buttons are super comfy, strap buttons(!) are tight and you'll likely never find these two being sold together again anywhere."

Korg Poly Ensemble S SN 770145

via this auction

"Korg's Polyphonic Ensemble S arrived on the scene in 1976, one of many preset-based analog string and orchestral instrument synthesizers at the time. It was manufactured in Japan by the Keio Organ company (aka KORG). However, during this early period in KORG's history, the name of this synthesizer has become somewhat confused. The KORG distributed units are named the Polyphonic Ensemble "Orchestra" and designated with the PE-2000 model number. Other units were manufactured for Unicord, presumably as part of a distribution deal outside of Japan, and they were named the Poly-Ensemble "S" and designated with the K-5 model number. There are no technical differences between these models, and in this article we will refer to them as the Polyphonic Ensemble S."

Grainy Autumnal Ambient Excursion With Model:Cycles And iPad

video upload by Perplex On

"Went for a walk in the woods, accompanied by the Elektron Model Cycles and an iPad. All tonal sounds coming from the Cycles which is sequenced by #fuguemachine on the ipad. #Polythemus app distributes the midi notes over all 6 tracks on the Cycles in a random manner, resulting in an ever slightly changing tonal quality of the chords. The glitchy blips and blops are coming from #fractalbits, sequenced by #riffer. Additional fx sends with a pinch of #rymdigare, #bleassmotionfx, #bleassfilter, #bleassgranulizer, #scatterbrain, #klevgrandrum and #velvetmachine."
