Author	Topic: Working on the BIT of the signal
paralleke Member	posted 26 September 2012 01:59 Hello all - GiGi here! Few days ago i had a look at the OTO BISCUIT by OtoMachines. Its a bitcrusher (8-bit AD) with this nice feature of muting/inverting each single bit from LSB to MSB. So i was wondering if this is possible in Kyma....im pretty sure for a Yes...but i didnt find-so far-a prototype for doing this.. Im actually a newbie and i still haven't arrived at the third section of "Kyma•X Revealed!" book....so i think: if not possible immediately-it would be possible later...programming it But -from your knowledge- anyone tried this out? Thank you very much in advance GiGi d-.-b IP: Logged
SSC Administrator	posted 26 September 2012 11:34 Hi GiGi, If you want to crush the signal down to 8 bits, you could do it by first attenuating (thus losing all but the top 8-bits) and then adding gain to bring the 8 bit signal up to the audible range again. In other words, first attenuate by (2 raisedTo: (32 - 8) negated). Follow this by a Gain of (2 raisedTo: (32 - 8)). IP: Logged
paralleke Member	posted 26 September 2012 12:46 Hi ! I gave this a try but it seems i get no sound at all... What i did on the signal flow is: Oscillator > Attenuate (Level) > Gain (Level) > Out Oscillator is a simple sine-wave; Attenuate has in its LEFT-RIGHT fields: (2 raisedTo: (32-8) negated) Gain has in its LEFT-RIGHT fields: (2 raisedTo: (32-8)) What am I misunderstanding?

BenPhenix Member	posted 26 September 2012 15:56 Here is an old thread about bit crushing and the different approaches whether using a Capybara or Pacarana: http://www.symbolicsound.com/cgi-bin/forumdisplay.cgi?action=displayprivate&number=7&topic=000319 Included are some prototype examples. If you ever come across one of my old sounds on the tweaky (like some of the Delays) that the bit crush feature doesn't work, it is because they haven't been updated for the Pacarana.

Actually...it was not...it was on the deafult value it has when I drag'n'drop the prototype from the browser. Now i got a first result! Thank you very much =) Need to investigate more now.. @BenPhenix: I'll take a look on your suggestions...thank you very much! Thanks guys GiGi d-.-b update Actually I still get no sound with OSC's Envelope at 1. I need to multiplicate the Gain fields for a value, say !Vol. In this way i hear the squared sinewave. Otherwise the signal flow doesn't sound. It's weird for me because it's only a matter of this multiplication factor in the parameter field...I play the Sound (ctrl+bar) - i dont' touch the Vol fader (so I don't change the value coming from [2 raisedTo()32-8]] ) in the VCS and THERE IS sound... With no !Vol in the parameter field i get NO sound... [This message has been edited by paralleke (edited 27 September 2012).] IP: Logged
