Not sure what the policy is here on requesting custom vst's, so forgive me if it's not the done thing.
I recently bought a V-Machine. It's a little underpowered, but overall it's great. I put GLoop on it, and it works pretty well, but as the V-Machine has a particular internal mixer setup, I really think that a custom made looper would really turn it into the ultimate looping tool. The internal mixer has 4 channels (that can load 3 vst's each) and then 2 fx channels with sends:
So basically, I'm willing to put some money into this, and I also think that if I post a request on the V-Machine forum, that I can probably get a few others interested in chipping in too.
So, if anyone is interested in this, please hit me up on info @ ishfaq .co.uk
The VFX app can be downloaded and used for free, so you wouldn't need an actual V-Machine to test stuff.
