reason question thats been on my mind a lot lately

this has been in my head for a while, but the "127" thread just made me curious again.
in reason the sliders for most parameters range from 0-127 or -63-+63(64?).
when modulating lets say the mod wheel, you can set it to control parameters by a certain amount.... i guess what im trying to ask is do the parameters jump in steps of 1? or can you get a step of <1? also what happens when you reach the maximum or minimum value? does it flatten out the envelope or will it somehow goe past its normal range?
thanks

dunno, but thats a deep question
i think that they cant go lower than 1 step per interval because they are midi emulations, and midi can only handle 128 different settings... i THINK, im not too sure about that tho.
we need a smarter person than I to clarify.

I don't know anything about reason, but in midi there are 128 possibilities. With a decimal, we're talking about more than 128 possibilities. Sometimes midi controllers are composed of two signals/two seperate pots I believe. Buttons are usually on or off composed of a signal of iether 0 or 127, depending on the state. Velocity, aftertouch etc etc are all 0-127.
If you have the mod wheel controlling a paramet by let's say 1/10th of the sweep of the parameter per each 1 bit movement of the midi controller, then you can still only get to 10/10ths, so the parameter will stop at its cieling, flattening. I think this is what you are asking.
I've not used much midi, but I used to be a programmer, so I"m mostly basing my understanding on observation and programming experience. I'm sure there must be some other kids here that are much more knowledgable about hardware and midi signals.

Yes you can.
You can for example limit the range of a controls and then use 128 step to scroll through the limited range.
For example I can use the mod wheel to adjust the master tempo in ableton. If I do not limited the range when I change the tempo I get very large tempo jump. However Ableton allows you to limited the range of master tempo from between 125-155 and then when I move the mod wheel I would be changing the tempo on increments of about .03 BPM for every step. It would take 128 step to get from 125 to 155 BPM.
Ableton is very fancy for allowing you to customize your controls.
You can also make up your own MIDI controllers using 2 special MIDI commands called RPN's and NRPN's which when used together allow you to get a 14 bit encoders or about 16000 steps.
MIDI is fairly flexible but it can be a headwreck.

this man is right

i was beaten to it by other geeks! i wanted to explain this and sound all clever
Midi systems make me wet.
