The preset manager has been updated. This new version have two new features:

1 - Saves parameters as name/value pairs [1], and so it should not be dependent on the order/placement of objects in the patch.

2 - Introduces a new attribute called "savemode". The "Global" mode allows a single preset manager to save all parameters in the patch, including all sub patches. The "SubPatch" mode works like the previous version, except for point 1 above.

Edit: I just added a third save mode "SubPatchV1", which is the exact same functionality as the first version of preset manager. While I'm keen on the added integrity name binding gives, missing the integer spinbox parameter (and possibly others) is not so cool, and I'll leave this option in until full integrity can be ensured for the other modes.

There is currently a drawback to implementing point 1: some parameters aren't currently being registered by the patches (in xpatch.cpp), and they will not be saved. When this issue/bug in the Axoloti base software is fixed, all parameters will be saved as expected. Currently I have identified the integer spinbox (ParameterInt32Box) as not being registered, but there could be others. If you test this object, please watch the Axoloti console and see if it reports any skipped/missing parameters on save/load in SubPatch mode (in Global mode this can't be easily detected unfortunately) - if you spot any other non-registered parameters, recognized by not being updated on a load, please report here.

Apart from the missing parameter type(s?), it now works better, since data integrity is helped by storing the parameter names. There is one problem with that though: in Global mode, two equally named parameters in different sub patches will create confusion. This can only be fixed if the patches store a list of sub patches (in xpatch.cpp, I'm discussing this elsewhere with tb, and I'm hoping this can be included in the next Axoloti version).

Given a fix for the non-registered parameters and a sub patch list, this module will perform complete preset management, like we're used to from most synthesizers.

The file format version has been bumped from 1 to 2. If you have saved data with the previous version, it should still be loaded back, but that support will be removed with the next update.

[1] In the files, only a hash of the name is actually saved.

A family of audio routing switches

drj/switch/ser_par_1 - mono serial/parallel switch
drj/switch/ser_par_2 - stereo serial/parallel switch
drj/switch/ser_swap_1 - mono serial order swapping switch
drj/switch/ser_swap_2 - stereo serial order swapping switch
drj/switch/par_swap_1 - mono parallel output swapping switch
drj/switch/par_swap_2 - stereo parallel output swapping switch
drj/switch/fm4op_alg - router for 4 operator FM synthesis, ala TX81Z

status

Ready to use

description

These switches were made to cover for switchable FX routing in my patches, but they can of course be used for anything requiring the provided switching functionality.

The fm4op_alg object is for building 4 operator FM synthesis patches ala TX81Z. It has the 8 algorithms that the TX81Z has, with the difference that all leaf operators have a feedback loop available, not only operator 4 as in the TX case. If you do not want feedback, just turn down the modulation index for the operators in question (that would be part of the operators you supply).

Hi DrJustice,
Not sure if you take requests , but is there any chance of a triangular and sine LFOs with 120 degree phase outputs? those would be useful to create Solina-like "triple-chorus" effects. Thanks!

[sovietpop]

Hey DrJustice , did you remove the preset manager from git ?

[DrJustice]

^ The preset manager is back.

I don't know why it was gone (but it's a good thing: I want some other objects to be gone, or rather moved to different folders - must talk to Johannes/tb about this).

I don't know why it was gone (but it's a good thing: I want some other objects to be gone, or rather moved to different folders - must talk to Johannes/tb about this).

you removed it, in this commit... perhaps an accident?

commit from axoloti UI

the only disadvantage with removing, rather than moving it you can loose the commit/change history.
so if you need things moved, you can do this directly with git tools, or PM me if you need a hand.

(perhaps worth pointing out to others... if you accidentally delete something we get it back, such is the wonders of version control... nothing is lost )

[DrJustice]

Ahhh... yes, I should've checked the git history. I did the move from here - seems fine in the repository.

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.

[gabriel]

Wow, that was quick! Many thanks!

[Sputnki]

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

Ah... silly thing done during a clean up pass. Fixed now. Thanks for the report!

MIDI/clock syncable delays and LFO

drj/delay/read_sync - delay reader with sync and modulation
drj/delay/read_interp_sync - interpolated delay reader with midi/clock sync and modulation
drj/delay/read32_sync - delay reader with sync and modulation, 32 bit

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

Here is one of the examples performance sequencer patches, seq_test_6.axo:

This is a set of 'studio' style stereo delay effects. The come in four variants to cover modulation and midi/clock sync. The default max delay time is 1.36 seconds - edit the sub patch to change that.

[sovietpop]

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

[rbrt]

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...

[DrJustice]

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.
