Phase Driven Sequencer from Hetrick; shift the start step possible?

hello, i want to create a patch for a phasor sequencer with the possibility of shifting the start step like with Bogaudio Addr-Seq.

e.g.:

from 1,2,3,4,5,6,7,8

to 3,4,5,6,7,8,1,2

i think about a shift-register with 16 steps, or manipulate the incoming phasor. but don’t know how. @trickyflemming

any ideas?

I haven’t looked into the phase sequencer yet, so I might be saying something stupid. Perhaps Carousel (Count Modula) would do the trick? I use it for roughly that purpose, but with “conventional” sequencers…

I don’t know the behavior of the Hetrick Phase Driven Sequencer, but if it wraps properly, then you can simply add an offset to your phasor to establish a different start position.

By wrap, I mean that if the phasor rises above 10V, it wraps back to the beginning of the sequence. If it falls below 0V then it wraps to the end of the sequence.

thank you, i just test it. but as far as i see, it does not wrap above 10V. therefore i have to do something manually. any idea?

unfortunately it only has 8 inputs. i need 16.

Maybe this ?

I believe Hetrick Phasor Shifter is what you want, though I have not tested it.

I assume that you set the Steps equal to the number of steps in your sequencer, activate Quantize, and then adjust the starting step with the Shift. Patch your phasor to In, and the Out to your sequencer. Again, this is all hypothetical, since I haven’t tried it.

I think @DaveVenom pointed you in the right direction. Try Hetrick’s Phasor Shift module.

In the example, each reset (Push) to the Phasor Generator starts (resets) the phasor at the point defined by the Shift knob of Phasor Shifter. When the phasor reaches the top (10V), it wraps around to the bottom (0V), which would be step 1 of the sequencer.

Phasor shifter works quite well( remember to quantize to your needs) but I sometime use the phasor like P16 from DocB. Send it the clock signal from one of the phasor modules and it can output permutations of the sequence, the simple P16 has 100 permutations and the P16a can program any sequence order you like, and feed this to ADDR CV in.

thank you, i patched a similar thing, but here the phasor does not wrap. i have to check that. will report here if i have a solution.

Perhaps you can try the patch; this should wrap.

And don’t forget Phasor Quadrature and Octature, these and a switch make resets to diff steps easy.

i just read about the octature. is it true, that i can set a start for every second step with it for a sixteen step sequence? can i patch a second octature into 180 degree output to select all sixteen steps? or do i miss something?

Yes, It’s Phasor math. If you have an 8 step sequence octature can select each step because it has eight equal divisions of phase. If you want smaller divisions use the shifter and set the division you require with the quantize and number of steps. Of course if you have 16 steps Octature can select , 1,3,5,7,9,11,etc. I do not think turning this 180 will get you every step, but a new ordering of the same steps. Use the shifter for these 22.5 degree shifts in phase. The quantize feature makes it simple, it will only send a stepped phaser that land directly on the steps, just like the DocB p16,p4 type tools. These address sequencers have become vital to me, as I like to create note collections in the sequencer and scramble their order, audition the best new orderings and sequence directly to those orderings with p16 cv inputs.

this thing can be set to ramp up and has phase control:

zzc phasor stuff is really nice for those types of things

thank you, that works as expected. now i have two detail questions:

  1. is it possible in any way visualize the step i am on?
  2. is it possible to mute the steps before the selected start? e.g. the sequence is running 3,4,5,6,7,8,1,2 now i want to mute 1,2 as a rest, not skipping.

do you know a way to quantize the output into steps? e.g. 16 steps in my case.

I assumed you were using the Hetrick sequencers, they are both visual as far as step location and able to turn off gates as they progress, As long as the cv is taken from the sample and hold output, you only get cv changes on an active gate.

I think it should work with this one:

thank you, i know this module. but it is not what i want. let me explain: if i set the startstep to step 3 i want display a three. on a led or display. like display on a sequencer module.

if i set length to 14, i want display 14.

hope i explain it better.
