lil ambient sesh - *moving day* (NORNS rachim JAM)

video upload by tworoundrobins

"deep apologies, but no talkie this week. I heavily underestimated how much work moving flats would take me...I did manage to record a short jam however and will be returning to talkies next week! thank you for your patience and and thank you for sticking around!

i'm using a new script by infinitedigits called rachim and it sounds massive! it's using it's own SC engine and the ears don't fool you - it does sound absolutely wonderful. do give it a spin!

pikocore with midi out

video upload by infinitedigits

"there is a new version of the pikocore firmware available (v1.3.0) which automatically assigns each button a note. the note can be changed by holding the button and turning the leftmost knob.

anytime the pikocore is plugged into a midi receiving device it will send out midi notes for each step. you can quickly get sequence variations by turning up the 'jump randomness' which will randomize the sequence.

here I'm using an online tool called 'midi2midi' (google it, second result) which can automatically push midi from one device to another. here I'm sending midi out from the pikocore into the roland tb03."

bloom

video upload by infinitedigits

https://github.com/schollz/bloom

this script aims to replicate the “bloom” app by Brian Eno and Peter Chilvers that was released in 2008. the major functionality persists: clicking on the grid / screen will create circles and sounds that grow and disappear. multiple touches will create sequences that also eventually fade away. the sounds belong to scales with alien names like "ambrette", "benzoin", "bergamot", "labdanum", "neroli", "orris", "tolu", "vetiver", and "ylang" - all which were painstakingly captured from the original app (PARAMS > scale). also, like the app, the norns script has an “evolve when idle” function (PARAMS > evolve when idle), and toggles for randomization (PARAMS > randomize).

there are major differences between the "bloom" app and the "bloom" norns script. its difficult to obtain 100% the same sounds of the app so I did my best with my synthesis knowledge to create a similar sounds with SuperCollider. the sounds I have are a bell-like feedback sine sound which can be mixed with a kalimba sample (swapping between acoustic and synthetic) (PARAMS > blend). the drone notes are taken from the scale, as in the app, but the switching between drones is not precisely the same.

another change is the introduction of "lanes" (PARAMS > lanes). this essentially splits the grid into multiple lanes where each lane is a separate sequencer. by default there is one lane, but you can have one lane for each row on your grid.

itty bitty midi (with pikocore)

video upload by infinitedigits

"https://ittybittymidi.com

here I'm syncing the pikocore clock and start/stop and beat resetting to the midi output from the roland tb03.

the pikocore midi syncing works using a small device I call the "itty bitty midi". the "itty bitty midi" has a midi input (DIN or trs type A) which is converted out to a serial stream that can be read by the pikocore clock in. the "itty bitty midi" device can be found on my wares website (link in bio) which you can get directly from me or use the schematic to build your own (its open source and only a few components - a DIN, a resistor and two caps at minimum).

the pikocore firmware can be updated to use midi with the online tool (also link in bio) with options to change the midi clock division, synchronization behavior, etc.

hopefully in the future I can get the usb midi working too...but not quite yet. still a goal.

and just a note that I've totally floored by all the astounding pikocore creations - music-wise and hardware-wise. there are now several alternative pikocore firmwares out there (link in bio) which can be used to make pikocore become different things, which is totally amazing and just shows how incredible open-source can be. never stop!"



"itty bitty midi a simple circuit that takes either a midi din input or a midi trs type-a input, and converts it to a logic-level serial bit stream. the resulting bit stream can be used by *core devices (like the pikocore) to listen to midi signals directly through the clock inputs.

there are two versions of this product, select the one that suits you: the active version utilizes a battery-powered circuit with the 6n138 optocoupler to effectively isolate the downstream and upstream devices. the passive version does not use isolation and has no battery.

the itty bitty midi is open-source."

Broken beats w/ Pikocore, Dirtywave M8, Roland J-6, TE TX-6

video upload by Arman Bohn

"More experiments with the pikocore. Random chord triggering sent from the M8 to the J-6. The Pikocore is synced to the J-6 which is clocked to the M8.

I’m syncing key changes to the random chords as well. I think I’ll continue down this path towards actual pseudo random song creation … so possibly more M8 + J-6 combos in the near future. The modulation options on the J-6 are nonexistent sound design is incredibly limited. I could use another mini synth instead, maybe the great conjunction, or the kasser arcade. but that would take more cord wrangling in the m-8."

This is the first post to feature the pikocore.

Another Wasp improv this time with Norns

"Still getting to know the Wasp again after all these years (and through something better than a cheap guitar practice amp ;-) ). I so need to sort out my workspace and up my production values a bit but stupidly busy as ever and prefer to spend my music time playing rather than sorting things out right now :-)

"everything" by infinite digits, live | norns, po-32, korg monotron delay, raspberry pi

video by infinitedigits

"a live performance of the last track on my latest album: https://infinitedigits.bandcamp.com/a...

the entire album was made with the cheapest synth on the market: the korg monotron. i hacked it to use midi from a raspberry pi. i added drums with a po-32 and mixed it live with a koma field kit."
