**This sensorizer project (version 0.2) uses an outdated GUI. There will be no further developments; instead go and build the new ACSensorizer - there have been made major improvements in the GUI/HUI => [[ACSensorizer_basic|AC Sensorizer 0.4]]**

====== Description =====

**//AC Sensorizer sensorizes up to 8 sensors and interpolates its AIN-readings.
The main target of this application are sensoric devices delivering not exactly 
0 - 5 V, like pressure-, distance-, resistor-based sensors or softPots.//**

:!:\\
This is a preliminary beta-release.\\
Use and build at your own risk!\\
There have been made major improvements in the GUI/HUI within the **newer release called [[ACSensorizer_basic|AC Sensorizer Basic]]** ...\\
The **Sensorizer Stage** (this one here) will be updated later on, but it is very likely that one more DIN and some more Encoders will be added!

Note: \\
//The Sensorizer is attached to a Computer which converts the Controller Messages – produced by the Sensorizer – to harmonized and clock-synchronized Note-Signals. I'm using Absynth Sounds ...but due to the buggy versions I'm looking forward to use a hardware synth somewhen //

===== Features =====

  * supports up to 8 sensors, code can be adapted to use more (eg with PIC18F4620)
  * enable/disable single AINs
  * slowdown: slows down the signal and increases the gaps between generated values
  * assignable CH and Controller-Number
  * sense-min: 10bit value, ignores every signal below
  * sense-max: 10bit value, ignores every signal above
  * sense-factor: used for signal interpolation... uses fast bitshifting or complex division depending on value
  * AUTO-sense feature: auto-calibration of sensor, detect MIN/MAX by sensing automatically adapts sense-factor!
  * scale from and scale to: scales the output value from/to
  * invert signal
  * pedal modes:
    * filter => only forward if pedal down; 
    * panic  => send panic on release pedal; 
    * combinations of all pedal mode options are possible 
  * detect release: send 0-value if signal drops below sense-min
  * bankstick support: 1 connected bankstick provides 2 banks with 127 patches each
  * midi configurable: full configuration possible with NRPN-messages 
    * NRPN-MSB CC99 for sensorSelect / sysEx mode

  * HUI-Input to control up to 4 sensors with 8 switch-encoders, pedal, store- & panic-button in 2 modes (PLAY/SETUP)
  * ACSim Console Debugger: code integrated and ready to use configured for XCode2
    * select "ACSim" as target and test the application via command-line
    * inspect variables with a (graphical) debugger (GDB support within XCode2)
    * visit http://www.midibox.org -> there's a tutorial how to use Code::Blocks





\\
===== Required hardware===== 

**MBHP Modules:**
   * one MBHP_CORE module
   * one MBHP_LCD module (5x20 optimized, 2x16 available)
   * one MBHP_DIN module for
		* 8 Encoders (preferrably with):
		* 8 pushButtons
		* 1 mode-select switch
		* 1 pedal (optional)
		* 1 PANIC button (optional)
		* 1 STORE button (optional)
		* 1 UP & 1 DOWN button (optional)

**Sensors:**
   * up to 8 (default: 4) sensors connected to unmuxed AIN (J5 of MBHP_CORE). Note that sensors 5 to 8 can only be configured via MIDI by sending NRPN-messages

====== Application Software ======

  * [[http://www.audiocommander.de/downloads/midibox/m5_sensorizer_024.zip|m5 sensorizer v 0.2.4]] (348 kB), download from http://www.audiocommander.de
  * [[http://www.audiocommander.de/downloads/midibox/m5_sensorizer_024_readme.txt|readme.txt]]  ...you should really read this, even if you're not recompiling the software!

\\
//Version History//
  * 0.2.2:
    * initial release
  * 0.2.3:
    * removed MidiTrough and used MIOS_Merger
    *	some minor bugs
    *	two example miniAudicle/Chuck NRPN scripts are now included
  * 0.2.4: 
    * fixed severe bank select bug that prevented accessing even banks

\\
//Compiling Notes//

The application can be recompiled with a variety of strictly separated #define-
options. For example setting SENSORIZER_INTERFACE_HUI to 0 compiles the application 
without hardware input controls and therefore reduces the file- and application space.
Compiling without HUI, BANKSTICK, NRPN-Config and LCD generates code with approx. 3 or 4 pages; compiling with all options will result in an application file of approx. 12 to 14 pages.

====== MIDI-Controllable Parameters ======

All Sensorizer parameters can be controlled and set by sending NRPN messages by MIDI: 

1. Send NRPN MSB (Controller# 99) to select control type\\
2. Send NRPN LSB (Controller# 98) to set the control parameter\\
3. Send NRPN Data MSB (Controller# 6) and NRPN Data LSB (Controller# 38) to set the parameter value\\

\\
^ NRPN MSB | | | |

| CC99, 0x63 | 0..7 | Sensor 0..7 | See Table B |
| CC99, 0x63 | 126 | SysEx mode: ON | n/a |

====== HUI-Controllable Parameters ======

:!: **The design of the Encoders is about to change with the next version. I just had one DIN at hand and the whole project had to be finished in time; with a second DIN and 4/5 more Encoders, everything will be a bit handier...**

If you build the Sensorizer with enabled HUI-mode, it provides configuration possibilities for 4 sensors. However, you could change the code easily to support all 8 sensors.

Used Hardware:
  * 1 Mode-Switch button (PLAYMODE <-> SETUPMODE)
  * 8 Encoders with Switch, two Encoders per sensor, the first row of encoders is called ENC_MIN, the lower ENC_MAX
  * 4 Buttons (UP, DOWN, STORE, PANIC)

\\
^ Function ^ Encoder(s) ^ PLAYMODE ^ SETUP-MODE ^
| Turn     | ENC_MIN    | slowdown factor | scale from |
| Turn     | ENC_MAX    | send value      | scale to   |
| Press & Turn | ENC_MIN | CH (MIDI Channel) | senseMin (10bit) |
| Press & Turn | ENC_MAX | CC (MIDI Controller) | senseMax (10bit) |
|       | | | |
| Press | ENC_MIN + ENC_MAX | sensor ON | AUTOSENSE_MIN |
| Press | ENC_MAX + ENC_MIN | sensor OFF | AUTOSENSE_MAX |
|       | | | |
| Press | PANIC + PEDAL | switch PEDALMODE (Mode 0 to 7) | |
| Press | PANIC + ENC_MAX | switch RELEASE DETECT (ON/OFF) | |
| Press & Turn | PANIC + ENC_MAX | senseFactor (0-32) | - |
//  Table C: Encoder Controls//

====== BANKSTICK Patch Description ======
m5_sensorizer supports writing and reading to a connected bankstick.\\
Each patch consists of 2 pages ˆ 64 bytes => 128 bytes\\
2 banks with 128 patches each are available per 1 connected bankstick

Sending a PRG_CH message in PLAYMODE [P] loads the corresponding patch.\\
Sending a PRG_CH message in SETUPMODE[S] sets the corresponding patch without loading the patch data. Use this behavior to copy patches.

Choose the appropriate bank by sending a Coarse-Adjust Bankselect (CC#0).\\
In HUI-Mode, switching a bank on the device also sends the current Bank/PRG.\\
