Simple Step Sequencer

stepseq.lv2's Issues

Add step count UI control

A some way to specify step count at edit time will be useful. For example xN multiplayer in style of step duration control.

semitone values cannot be altered

I saw this was just updated and decided to give this a go, I noticed the plugin works nicely and if one more thing: is it possible to set the numberic values beyond 2 semitones? I'm not sure if this is intentional or if it is really a bug. I think it may look more like a bug, as it is a numeric value and so users should be able to change it dramatically beyond two semitones..

thanks

MIDI input

Can it be made possible to control the sequencer using midi input? For example I have a hardware midi controller and I'd like to use it to control the sequencer.

make instructions

nice project, but amending notes for the make instructions I think can definitely help..
here it wouldn't compile without the additional notes coming from the bugreports,
#3 (comment)

thanks

Doesn't sync fluently in Carla with jack_link / Ableton Link

Not sure if this is a bug in Carla or stepseq8x8

Feature Request: Configurable sequence length (upto max)

By the way I really appreciate all your plugins! Thanks for all the work you have put into the development of them.

Would it be possible to add support for a configurable sequence length (upto the hard coded max) that would allow support for sequences of different time signatures.?

I want to create drum beat sequences for different time signatures (say 3/4 or 5/4 or 7/8) and am using the MOD Dwarf. Right now there exist a few variants of your sequencer, that support say 8x8, 16x8 or 32x8 sequence grids however from my testing they only really support time signatures that are an integral multiple of the max sequence length as the sequence loop step is always fixed based on the step size of the sequencer.

If however there is a parameter that allows to configure how many of the steps are part of the sequence so instead of say for a 32x8 sequencer where it currently always loops at step 32, would you be willing to add support for a new parameter that allows it to loop at step N, where 1<= N <= 32 ?

The goal would be if the loop size is set to say 14 on a 32 step sequencer, then I could program in a 7/8 beat fairly easily as 14 is a multiple of 7.

Then we would be able to support custom length sequences (upto the hard coded maximum for each sequencer) allowing much easier support for different time signatures.

Question: Build of stepseq_s16n8.lv2 or stepseq_s32n8.lv2

Hello, Robin!
I've downloaded and tasted:
Linux 64bit
v0.5.0 2019-01-23 4.42 MiB - this works well!! Thank you very much!

Do you plan to make some "ready to use builds" of stepseq_s16n8.lv2 or stepseq_s32n8.lv2? (It's not enough steps for my percussion parts :)) ).

Or may be you can order me in my monkey's steps in compiling through your instructions...

I try to compile stepseq_s16n8.lv2

I do:

git clone git://github.com/x42/stepseq.lv2.git
 cd stepseq.lv2

After that I open Makefile and change steps to this:

# grid-size (should be at least 4x4 for the MOD-GUI)
N_NOTES ?= 8
N_STEPS ?= 16

than I do:
make submodules

in the terminal I got:

cooltehno@cooltehno-Sys:~/stepseq.lv2$ make submodules

than I do:
make
and got:

So, I do again:

and after all I do and got this:

After that Ardour can find plugin in the list (finds it in /usr/lib/lv2/stepseq_s16n8.lv2),
but can't instantiate.
(from Ardour log):
[ERROR]: LV2: Failed to instantiate plugin http://gareus.org/oss/lv2/stepseq#s16n8

Great Thanks!

misc/Makefile missing in 0.6.0 release

misc/Makefile is missing in v0.6.0.tar.gz. The file is necessary to build the plugin for specific number of steps and notes.

A panic button stops playing

If hit a panic button the sequencer stop playing.
Plugin version 0.4.1 tested with Ardour 5.11.

X42 plugin - stepseq with more functions?

Would it be possible to equip a sequencer with the following functions?
Personally I would find it very musical if the sequencer

Global:

• Swing
• Directions (…/forward/reverse/alternate/pendulum/random/brownian/eitherway/…)
• Timebase (1/2/4/8/16/32/64/2T/4T/8T716T/32T/64T)
• Bar Length
• Sync
• ReSync
• (Force to) Scale
• .

Per row:

• First Step
• Last Step
• …

Individual for every note:

• Velocity
• Length
• Delay
• Probabilities / Accumulator Events
• …

would support.

I got to know and appreciate these functions through the Cirklon

Use HTTPS for robtk submodule

Small question :)
Can you change the robtk submodule URL to use HTTPS instead of git (so https://github.com/x42/robtk.git)?
Using git as a transport isn't really secure.

Dynamic step count?

Would it be somehow possible to have a dynamic step count?
I.e. for instance 1 of stepseq.lv2 I want 8 steps, but for instance 2 I want 32 steps.
