A set of phasors and sine oscillators with phase reset/sync and phase modulation. These were "leftovers" from a request, and have basically only been moved into the drj/osc folder and published.

Wow, that was quick! Many thanks!

You're very prolific in what you're doing :blush: the sine bipolar with reset is THE THING. I can see (hear) solid kick drums coming

MIDI/clock syncable delays and LFO

status

description

Two 16 bit readers (one is interpolated), two 32 bit readers, and an LFO which can be synced to a clock pulse or to MIDI clock. The modules are phase locked to the sync source.

The delays have both an absolute time input (as for the original delays) and a proportional time modulation input.

The 24PPQ clock input doesn't have to be 24 Pulses Per Quarter note - it's just labelled that way for the sake of convention. The MIDI and 24PPQ clocks can be divided down using the clockdiv parameter.

This is a set of objects to facilitate the mechanics of berlin school sequencing,

The emphasis is on performance controllability and fun factor. Therefore every control is accessible so it can be bound to MIDI CC, either on knobs directly or via control objects connected to the performance inputs.

The core is the sequencer clock controller. This controls the how the steps are played in a number of ways. The clock is syncable to MIDI or to a clock pulse input, as well as having an internal clock. The sequencer step value blocks use dials in order to make them CC assignable.

There are a few patches that demonstrate the use of these objects. These patches make use of a delay sub patch which will described separately:
drj/seq/seq_test_1.axp - drj/seq/seq_test_7.axp

Using axoloti for MIDI syncable stereo/ping pong delay?
#30

Wow , lots of good stuff ! Thanks for your contribution DrJustice :slight_smile:

#31

really really nice!

...but any idea how to set a certain step of the 'stepseq_16_switch'
from the 'outside' ?
for example via an additional input 'set step',
the 'parameter_s1' in your object will
be set to the value of 'set step' if inlet_step == 1 ,
the 'parameter_s2' in your object will
be set to the value of 'set step' if inlet_step == 2 ,

and so on...

#32

Setting parameters from module code can be done to a degree, but not reliably (the issue of parameter access is being discussed elsewhere). The method you describe could be implemented, but the buttons would not reflect the step enables taken from the dedicated input.

An alternative module could be made for this, not using the current button parameters, but making a switch module that is meant for external control. It could have a display to reflect the state of the switches. In that case the design is open for implementing your suggestion and any useful additions, while still being controllable by MIDI CC (an explicit goal of these modules). One could also use momentary buttons for toggling the step enables and then use a display element to reflect the states - that would accommodate your suggestion while keeping the display up to date.

#33

Ah!

Setting parameters from module code can be done to a degree, but not
reliably (the issue of parameter access is being discussed elsewhere)

...just found the thread,but it's a bit to DEEP for me at the moment...

It could have a display to reflect the state of the switches.

how could that be done,practically ?

anyway,I got to where I wanted to get by using a 16 - sample buffer,
but this approach doesn't reflect the actual sequence in the patcher UI,
AND, more important, the buffer is not visible to your 'preset manager' (which is simply GREAT)
(you can save/load the buffer to sd-card anyway,so it's working as I meant it to)

so,conclusion,it would be great to have a SIMPLE way to set UI elements programatically...

description

A set of MIDI Non Registered Parameter Number receivers. The "multi" variants are for advanced use where on might want some or all of the value formats, as well as triggered reception.

The chmsb outputs generates a pulse when the MSB portion of the NRPN value is received, and the chlsb output generates a pulse when the LSB portion of the NRPN value is received - the latter indicates the complete reception of a 14 bit value, when both the MSB and LSB values have been received, and can be used to ensure the integrity of the full 14bit discrete value.

The multi2 variant receives all NRPNs and has an nrpn otutput to indicate the last received one, whereas the other variants receives only the NRPN set by the nrpn attribute.

Tap tempo

drj/seq/tap_tempo - tap tempo clock generator, live mul/div
drj/seq/tap_tempo - tap tempo clock generator, attributes mul/div

status

Ready to use

description

This is a pair of Tap tempo clock generator modules. The tapped tempo is multiplied and divided by clockmul and clockdiv. If you want e.g. a 24 PPQ (Pulses Per Quarternote) clock and want to tap 4ths, set clockmul to 24, set clockmul to 12 for tapping 8ths etc..

The tempo can be tapped using the built in button and by using the boolean tap input. The tapping is set to time out after 5 seconds to avoid super slow tempos on the first tap in a series.

The clock output emits pulses at the tapped tempo * clockmul / clockdiv. The phasor output emits a positive ramp at the same frequency.

The first version uses live parameters for the clock multiplier and divider and the second uses attributes for a tiny saving of CPU power

Note: the other _sync series modules can be tapped by setting the sync source to external and "tapping" the 24ppq (clock) input.

Hi. Just testet out the syncable multiwave lfo. I could get it to lock to external midi sync, but never on beat. Sorry for being so ignorant, but I still got some problems. I set the device to OMNI. Clock source to MIDI. In pro tools i enable midi beat clock for the axoloti. I have nothing connected to the multi wave 24ppq in, since my logic tells me that it pics up the clock internally.
I then load up the patch. Press play in pro tools and eveything seems to lock fine. I then press stop, and press play again, and the sync lock is way off. I have the clockdiv set to 24 to give me a good 4 to the floor LFO modulation, with a square wave from the multi lfo, modulating an osc.

What am i doing wrong?
Thanks:)
