XY x 4 Pad Project

[Andrew J]

I couldn't get the right click to work with the dragXY - that's why I used the shift key instead.

This is amazing work gentlemen!

yes, indeed great project and great work here!

[noise_maker]

Really nice!
The Left+Right path record feature is very handy!
thanks for sharing it Martin all the others who help! amazing work!

I have a superrrr idea! but I have no idea how to implement it.

here it goes:

1. add a BPM button (to sync off/on)

2. while drawing a path (right + left+ drag), for every beat press Ctrl to add a beat mark# (1, 2, 3, 4...)

another suggestion: saveable paths

1. add a BPM button (to sync off/on)

Unfortunately, I'm a bit busy to contribute much at the moment; but my current project is using a form of 'motion recording' on its knobs. If I get the chance I'll see if I can modify the relevent parts to post up here...

In the mean time, if you search for 'Soopa Loopa' there's a Beta of the schematic there - the relevent part is within the knobs, called 'Parameter Looper' - you'll also need to delve into the tempo module to get hold of the clock generator that generates the timing signals - 'Beattime' is the length of one beat (in samples) and 'Masterclock' is a ramp waveform cycling every two beats (two beats is just a side effect of the clock being used elsewhere).
The main bit is hopped and interpolated, but the timing clock is sample accurate, so the BPM timing is much much better than in green, and the CPU is pretty low (could even use quad mono - two x,y blobs per code then) - sorry the code is a little convoluted, but that's so that it can follow tempo changes. (the main bit is in assembly, but there's a purgable module with the original code version)
I'll see if I can do some mods so that record and play are seperated - that way it could use a mem primitive, enabling paths to be saved as wav files.

That would exellent!

Here's my first draft of a modified motion recorder module - it may need a fair bit more tweaking to suit your purpose, but I haven't time just now to try and wire it into your x/y pad.
The length of the loop is rounded to the nearest beat from the length of time that record is active (that may well be the part that doesn't work so well for your schematic). The Master Clock is a wireless module so that it can be shared by several recorders easily.
Let me know how you get on, and I'll try to refine it more (unless somebody else fancies trying to make sense of my code ) - it could be a useful little module eventually for a lot of different things.

I too am very short of time so I hope someone else can dig into it? At least get it started perhaps?

[noise_maker]

Invector (SM synth - osm version) has a BPM based pad with 5 steps (4steps and the 5th close the beat).

it isn't as cool as drawing a path and click CTRL to add steps, but maybe it could be useful to understand few thigns (at least from my side)

[noise_maker]

when I link the balls to my midi controllers, the balls move only half way X/Y....

can you look into it please?
