Grainstorm with current Grid/Arc4

Curious if anyone is using Grainstorm with the current (2016) Grid and Arc 4. Are there any workarounds for the lack of push function on the newer Arcs?

I think @Alec_Brady wrote smth about a fix. His workaround I believe was to substitute the button push by a faster turn of the knob.

Thanks for the lead. I will check into that thread.

Stretta did that one!

@burke I first programmed this ‘fast turn’ workaround back in 2014 when the first ‘buttonless’ arc was released … Implemented it in a couple of patches to see how it would work. Also put it in Grainstorm. Patch and dirty M4L conversion in attachment (I didn’t use this for a looong time, but it should work). Also attached a maxpatch with some basic info on the ‘button to fast turn’ conversion. Feel free to implement into any other original arc patches.

Also did TML (M4L only) which I still use these days. Let me know If you want the device.

@ithkaa thanks for the info. I would love to take a look at TML if you can send the device. I will update this thread as soon as I can try out the Max patch you sent as well.
Much appreciated!

Hey @ithkaa! Is your version of grainstorm for Max7? I can’t connect any grid or arc because theay don’t even show up…
Any idea?

Perhaps i didn’t lock the device. i’ll taken a look at it tomorrow …

Hi @ithkaa,

I have finally been able to do a little work with your version of Grainstorm and it is working really well! Just wanted to say thanks so much for sending it and for tackling the re-code for the fast turn.
