Sequential Pro 3 Paraphonic Mode Fun - A Dozen Patch Demos

Creative Spiral

"Over the past few months, I've designed about 50 new 'Paraphonic Motion' patches on the Pro 3. This video is a demo/preview of a dozen of them. The Pro 3 has three LFOs, four envelopes, the 4x16x16 sequencer and the gigantic 32 slot mod matrix -- it excels with designing lots of motion and nuance into patches... it's really a sound designers dream synth for mono/para.

I've been having a great time building paraphonic patches and complex arps....taking inspiration from my favorite Korg MonoPoly sounds, plus designing a lot of "Adrenalinn" inspired filter/trem/mod sequences.

Let me know what you think! Any favorites?"

Jamuary 8 - Roland Boutique A-01 8 bit synthesizer jam

Expanding Sound

"Jamuary rolls on, today I decided to pull out the Roland A-01. I don't use it a lot other than for a bluetooth midi controller so i thought it might be fun to make a quick song using the onboard 8 bit synth for all the sounds. I thought it came out pretty fun. Hope you enjoy it!"

AcidLab Bassline 3 Synthesizer

via this auction

"Acidlab Bassline 3 in great condition. Has some mild cosmetic marks on the faceplate. Comes with manual and EU 2-pin PSU.

'Acidlab´s Bassline 3 is a very close clone of the Roland TB-303 and has been complimented on it´s authentic sound and behaviour often. Luckily the original sequencer is not implemented but one that is easy to use and that can be played live!

The analog synth part is very close to the original and is well-known for its punchy thick, very characteristic sound.

The oscillator has square and sawtooth waves and it´s frequency can be set with the tune control. The legendary lowpass filter has a cutoff and resonance control and in addition you can modulate the cutoff frequency with the decay envelope generator that´s decay time and amount of modulation can be controlled. The accent potentiometer determines the amount of accent.

The sequencer allows for classic 303-style sequencing with slide and accent parameters that can be set for each set note but it is much more friendly to use and has six different operational modes. The sequences can be saved in 12 banks with each 8 patterns. In Pattern-Play mode you can chain adjacent patterns from one bank. By copy and past copying patterns is easy, also copying into other banks.

Other features allow you to edit accents and slides in real time while the sequencer is running; you have different pattern lengths, two types of shuffle with 4 setting each, different clock dividers (in 4/4bar mode only). The roll function makes it possible to shift the start point of the sequence which is very handy when the perfect bass line just doesn´t fit to the rhythm: just shift the sequence instead of re-programming it.

In the Track Modes you can chain all patterns from one bank, in their original and transposed versions, to songs.

The Bassline 3 can be synchronized either to MIDI Clock or to DIN-Sync. A third position of the sync switch makes it possible to use the instrument as a master for synching other gear via DIN-Sync. You can play the Bassline3 with MIDI notes as well and also the accent (above a velocity of 100) and slide ('when two notes are played together) are playable via MIDI.

By the audio input you can process external audio signals thru the 300 filter. the cutoff frequency can be modulated by the FM input with a control voltage. Play other synth via the Bassline´s sequencer by using the CV and gate outputs. the accent output will generate a gate with +12V level.'"

Korg NTS-1 Stop Motion Animation Build Video

Nikki Synth

Using the Stop Motion Studio app for the iPhone, the Korg NTS-1 magically comes together.

The music is the NTS-1 with the drum loops and patterns being provided by Ableton and programmed by myself. The SQ-1 is sequencing a pattern, which was then recorded and arranged in Ableton Live 10 Standard. The interface used is a first generation UA Apollo Twin Duo desktop."

New Hammond Suzuki SK Pro Organ + Mono Synth Video

"HAMMOND - COMING SOON - January 10th, 2021" - SUZUKI

New video of the upcoming Hammond organ synth hybrid reveals the synth portion will be a mono synth. You can see some of the synth parameters in the display as well. It's interesting they went with a mono synth vs poly. Curious if it's analog considering. That or they want it to be used exclusively as a lead instrument.

You can see the following Oscillator waveforms:

Due - saw + saw
Unison - supersaw
Pulse - w/ modulation
Sync - w/ modulation
FM - sine x sine

See the Hammond label below for more.

"Still finding my way back into my music practice - a bit more of a conventional setup today. Been thinking a lot about Chris Randall's comments about why he got rid of his modular (paraphrasing: when he had the modular it became about the modular not the music)

Ignore my strangely swollen left hand - got some weird oedema crap going on - hopefully not serious, talking to the doctor about it later this week

Moog 1973 Model D Minimoog analogue synthesizer demo & tutorial


"In this clip, I test-drive a relic of 'synth history'. Revered by legends such as Herbie Hancock, Keith Emerson, J Dilla & Brian Eno to name a handful. This old boy here is one of the first 1500 to come off the production line way back in 1973. Sitting behind one of these is quite an experience.. the sights, the sounds... the smells.. of a hard working mono synth!"

Korg NTS-1 & Liven 8Bit Warps - Boating Lake Ambient - Jamuary 10th 2021


"The Liven 8Bit Warps in this video was kindly supplied by Sonicware

I'm super late with Jamuary and I suspect I'll be a little busy this year with other music based duties, but I'll try to join in where I can

This jam came about after experimenting with the midi out on the Liven 8Bit warps which sequence external devices, it also accepts audio from external devices though a stereo 3.5mm socket so it seems like a pretty good match for the Korg NTS-1 seeing as it has no sequencer

The 8Bit Warps sends sync, note and CC data from any knob or recorded knob movement, though I couldn't really find any midi CC's that matched up well with the Korg NTS-1 (cutoff for example is a different midi CC) so I stuck to adding a bit of variety by hand to the notes sent from the 8Bit Warps sequencer

The patch playing on the NTS-1 is 'Milk Bottle' from my recent NTS-1 Megademo video. The rest of the audio is synthesized on the 8Bit Warps then recorded and played back from it's built in audio loopers.

The video is some found footage of a boating lake I found on some mini DV tapes in an auction lot"

Arturia Minibrute 2S analogue semi-modular synth and sequencer

via this auction

I never noticed what looks like guitar strap screw holes on the side panels. Interesting.

"A lovely, sweet sounding synth with a very flexible filter, allied with one of the best studio- and performance-oriented sequencers out there - 4 tracks, capable of sequence notes alongside internal parameters and external CV. Also a great device for distributing USB/MIDI clock to a Eurorack system, or as a more general MIDI to CV converter."
