Octatrack Steampipe

Steampipish sounds attempts with Octatrack.

1 track to generate noise
Master track
Comb filters with feedback (track recording itself)

6 voices first in first video’s half, then 1 voice with dual comb filter and more metallic sounds, 2 different tunings…

Here is original Erica Synth Steampipe audio path…

Here is the project file. Use patterns D9 - D13 - E9 - E13 (banks 4-5, same as video).
Audio cables between CUE outs and IN AB.
Listen to MAIN. (Check headphones MIX)
Extract folder and place it in active set. Eventually save project first if you want to revert to original settings

Cool ! Could you please share a project file ?

Yep. I need to clean it to keep only relevant banks / patterns with their parts.

There is more to explore. I used different techniques, using recorders, or cue outs with thru tracks and cables…

Unexpected trick : a track recording itself and INAB for noise input : tame feedback with RATE pitch down. Tuning remaining the same forced by comb filter (example in video’s beginning).

Did you replicate the Steampipe’s architecture?

I came to similar results, using the noise of an Analog Heat. Will give different noise textures when simultaneously modulated via Midi.

Basically, but I use comb filters frequencies independently from the feedback loop time, and it forces tuning. They have their own feedback.

Steampipe allows to tune delays with a feedback loop with filters, envelope, drive, which is different.
I tried to use OT delay, 100% wet (DIR off). Not easy to tune : it is added to feedback time (64 samples minimum). Also Martin from 112db, Steampipe creator, said tuning also depends on filters in the feedback loop (low pass and hi pass) because they change phase.

(At 22mn in the video)

I have to try something that may work : tune feedback loop with pre slices…:wink:
I already used it for tuned recording loops.

Edit : slices works for precise tuning, but if recording is shorter, slice length become also shorter…doesn’t seem usable for live playing…

Cool stuff as always man!

Would love to have the project file to play with this.

You rock man I’ll try and check it out after work.

Octatrack is starting to turn into a real playground for me with the different templates I’ve built and downloaded from different folks, as a machine it can be so many things… Reaching the point where two octatracks might make sense LOL.

Thanks for keeping the dream alive @sezare56

I wonder if this is also related to the phenomenon with decay on filters that makes a fast decay make a note sound flat? If I understand the K-S architecture, you have a filter in the feedback loop of the delay that is kind of serving that function.

On the OT’s comb filter I hear that when turning down the LPF and the compensate with the fine-tuning pitch control.

Since the Steampipe is based on a Reaktor ensemble from the same maker you could probably reverse engineer it even more as you can just pull apart the Reaktor ensemble and see how it’s been made. :slight_smile:

Great work though in any case! :slight_smile:

Thanks, I know but I don’t use plugins anymore.
This picture below suffice to me (from Erica Synth), and anyway I have to cheat with OT. Steampipe uses complex tuning compensation when using lowpass and hipass filters in the feedback loop.
With OT comb filters it can force tuning.
