if you could set 6 params to a midi controller, what ones?

The MIDISense would definitely be cool to have when bringing your MPC out with you, as it's nice and compact. It would definitely be good for where work space is limited, as well as having an affordable alternative to other MIDI controllers.
I'd love to build one eventually and mount it in a small project box (like the ones I use for building guitar effects pedals).
From what I understand, the development of the MIDISense has gone further from the original, since the MIDIsense Analog+Digital I/O kit
v1.0 became available recently.

In addition to building a MIDISense, I'm also looking to build the Highly Liquid MPA MIDI Decoder. The reason behind that is because I'm planning on building my own drum synth with will have "trigger inputs", and this kit will allow MIDI-to-trigger conversion.

From looking at both websites, I'd definitely need both products in the future.

As far as what MIDI CC's I'd like to see in the MPC, there's just too many to list for me to decide on only 6.
That's very limiting. Any piece of MIDI gear that responds to MIDI CC's usually would be able to respond to way more than just 6 parameters.
Considering that the JJ OS2 is very synth-like with it's filters, filter envelopes, amp envelopes, pitch envelopes, LFOs, etc., I'd like to have external control over all of these parameters. I don't see why it's not possible.

Just a heads up to anyone who is at all interested in making one of these; my interest is growing every second just doing research. But on the website of the midisense, there is a detailed list of sensors that will work for it, obviously the temperature and gas sensors aren't really useful, but other than knobs and sliders and IR sensors, there are joysticks, switches, pressure sensors, ribbon controllers, and sonar distance sensors (http://youtube.com/watch?v=AtNC7yJiDd0) think that. This is truly customizable and you can make a couple with a full range of sensors on it.

distorted: the idea was not "choosing 6 params in the jjos2 that can be set to cc" but rather "if you had to choose 6 from the many cc-assignable params in jjos2, which ones would you choose and why?"

and i say limit this to 6 inputs, of course, because of midisense.

the nice thing is that the mpc could of course have many more than just 6 incoming midi ccs sending signals (i'm speaking from the future, hellloooooo there) so while at home, you could hook up midisense, an axiom, AND a bcf2000.

the "choose 6" thing is only for fun

We're gonna revolutionize the industry! This actually has me sweating, thinking about the live possibilities...

nym, this is directed to you, i talked to my brother, and there is a large possibility of me getting one of friends to put one of these things together for me, but the one question that i still have is, how do you choose what CCs it sends, is this done through the configuration program that is on the website?

yes, it's done via the software. you program it via the software, then the settings are remembered in midisense until you change the settings.

ok. that is what i thought. but i just wanted to confirm my suspicions before plopping down the bones for this.

the software is open source, too. ladyada is a genius, but unfortunately she has a LOT on her plate at one time. this isn't to say it doesn't work like a charm when you get it working (i had a LITTLE trouble, but it was all my own fault, not hers) but it does mean updates are not too too frequent and tech support takes a couple days.

i hope to eventually find a programmer who i can interest in tackling the midisense software in order to make a few key additions to the calibration options (currently you can set the LOW, MED and HIGH points, but i'd like to see a whole curve adjustment calibration system put in there)

glissando? stupid question, but does the MPC have this functionality now, or are you hoping for some amazing update from JJ?

@ nym

since you seem to have chated with jj about the cc implementation issue... is this going to be the next thing on his agenda? and when do you think will this be available?

jj and i last spoke about the ccs a while ago. last thing i heard was "after 1.00, probably in april" but that might be pushed on back due to the 2500 taking immediate precedence. so, it's coming, and i plan to send a little more mail soon but frankly i feel bad sending ANY suggestions or requests because the poor dude is BOMBARDED with requests and emails.

bruxism, "glissando" is a feature of midisense, not the mpc. when a sensor is set to GLISSANDO in midisense, the MPC is receiving your normal, everyday midi notes

so it wouldn't be truly like a theremin, ie, it'd just play the 128 note steps in succession, rather than a smooth glide, correct?

yes - unless you set portamento.
i don't plan to use glissando much in the mpc itself, rather thru the mpc into reason or olga, which is better suited to those needs/sounds.

the way i will be using glissando is the way i described earlier, taking a short clip and chopping it into 64 pieces and then "glissing" them in mid air, kind of like granular scratching.

this will by no means replace a theremin (which i don't have and have never used unfortunately)

but glissando is the function i've just kind of assigned to the IR, for now. it could just as easily be any other function as well. i mean, think of using it for sample start. when no hand is above it, it would give a 0 readout. when you start bringing your hand down, it'd set the play start ahead in the same. this is cool cuz there's an immediate return to 0 (full play) when you remove your hand (or face, if you position it so you can just lean in while playing)

cool, thanks nym.
