MPX-G2  -  Release Notes Version 1.10  4/24/02

All v1.00 presets are compatible with all the following changes and improvements.

Bug fixes:
Fixed the Delay(D) Delay(S) and Echo (S) and Echo (D) 5 second delay bug
Enter any of the above effects.  If the delay time is greater than 5769mS, left and right channel get a different delay time.  Some cross feedback is also heard.
Fixed DiatonicHmy bug that gave incorrect pitches for "down" pitch shifts
Setting the “Int” parameter to a “-“ pitch shift setting will give the wrong interval.
Fixed "sleep" crash bug that would kill box when you entered the tuner
Select the “System / Modes” submenu.  If “Sleep” is set to “Help” and the tuner is activated, the box will reset itself as soon as the Sleep timer times out.
Fixed footpedal tuner offset bug
If a MPX-R1 footpedal is connected to the G2 and “System / Tuner Mode / Tuning Cal” is set to something other than “A=440.00Hz”, the footpedal does not see it.
Fixed bug when transmitting MIDI display tuner cal units
If the G2 is connected via MIDI to a control program, the “Tuning Cal” units are always reported as “A=440.00Hz”.
Fixed MIDI Map bug that prevented access to banks over 100
When the MPX G2 is set up for MIDI maps in “Program / Options”, sending program change 111 from the MPX R1 makes the MPX G2 go back into “Sort by Number” and select preset 111.
Fixed possible crash bug in MIDI handler driver
A stack restore problem in the low level MIDI driver can cause problems when doing MIDI transfers.
Fixed Wah2 and PedalWah2 level difference when "pre-gain" bug
If Wah2 or PedalWah2 are placed in the pre-Gain path, the level at the output is down 3dB in level from what it should be.
Fixed MIDI Map clear bug
MIDI Map clear sets maps to "Clear Loop" instead of "unassigned".
Fixed Tap not working as a program change in MIDI Map to run JamMam effect
Enter “System / MIDI Pgm Maps”.  If “Tap” is selected for use with a program running the JamMan effect, it will not work as intended.
Fixed “sticky” output volume pot
If the output volume knob is moved very slowly at the low end of its range, the movement is not detected.
Fixed MIDI Map with a program number used more than once works incorrectly
If you map a program to two separate MIDI map entries, the entry with the smaller number will become the current MIDI Map program number.

Effect Changes:
 “BlueComp” time constant shortened so that '0' attack is more like '0'.
There is a minimum attack time set in the algorithm that is greater than '0‘.  The minimum attack time has been made faster so that the effect sounds less “crunchy” at the ‘0’ setting.
Added a new "Samples" option to delay units Options
Sample time is based on a 44100 Hz sample rate (22.7 microseconds per sample).  There is a lag time in the A/D and D/A convertors that set the absolute time through the box to a number of milliseconds.  The sample delay should be added to this to calculate the real delay through the box.  This Option has been added to all Delays and Echoes.  Neat resonance effects can be created by using high feedback settings and changing the delay time.
Added "Comp (S)" to Effect1 and Effect2
Comp(S) is a stereo version of "BlueComp".  The detector is mono (the left and right compressors are linked).  Otherwise, it is exactly the same as “BlueComp”.  Comp(S) includes the change to the “BlueComp” attack time mentioned above.
Added new "Ring Mod" effect to Effect2 and EQ
Modeled after the Big Briar moogerfooger™ ring modulator.  A locally generated sine wave carrier (Freq) is multiplied by the input signal creating sidebands around the carrier frequency.  A built-in LFO modulates the carrier for added weirdness.  Harmonics are not anti-aliased.

Mix	0-100%	Dry/Wet ratio
Level	Off, -89dB to +6dB	Amount of effect in processed signal
Freq	1-8000Hz	Carrier frequency
Bal	-50 to 50	Left/right pan control
Rate	0-50Hz or	LFO rate or period ratio
	1:24-24:1 cycles/beat
PW	0-100%	LFO pulse width
Depth	0-100%	LFO depth
Type	Sine,Trian,Squar	LFO shape: sine, triangle or square
Added Wah and Tone effects to EQ
The EQ group now has “SweepFilter”, “Wah1”, “PedalWah1”, “Wah2”, “PedalWah2”, “Test Tone” and “Ring Mod”.  These are the same effects available in Effect1 and Effect2.  You can now have a “Wah” effect and still use any Effect1 and Effect2 algorithm.
The "TestTone" notes param will display the equivalent frequency number
The TestTone effect in Effect1, Effect2 and EQ can be used as a sinewave generator with readout in Hz.  Press the "Options" button to toggle between a readout in notes or a readout in frequency.  Always defaults to “Notes”.
Compressor level in “Wah2” and “PedalWah2” shows in a meter on the display
The compressor in Wah2 and PedalWah2 is the same as RedComp.  The meter that shows in RedComp now shows in these effects also.

Improvements:
Add "Dry level" option to all effect Mix parameters
Press “Options” while cursor is at the “Mix” parameter (at the beginning of the Edit menu of every effect).  The Mix changes from a number with “%” to a number with “dB”s.  The Mix parameter now represents “Dry Level” and the  Level parameter represents “Wet Level”, as it always has.  The parameter label always says “Mix” regardless of the mode.  Note that the Mix parameter for “Panner” and “AutoPan” effects is not interpolated when in "Dry level" mode.
Added a Store name editor
An advanced editor for naming programs.  Press the “Options” button from the “Store” menu. All effect LEDs flash to tell you you are in this special mode.

The encoder selects words, numbers, and strings.  “<” and “>” move the cursor to select the edit position.  The effect buttons perform the following:

	Gain	Clear from the cursor to the end of the name
	Effect1	Select Word mode
	Effect2	Select Letter mode
	Chorus	Jump to lower case ‘a’
	Delay	Jump to upper case ‘A’
	Reverb	Jump to number '1'
	EQ	Drag letters from the cursor to end of name with rotary encoder
		while button is held

Help for any button appears if it is held more than 1.6 seconds.
Added an enhanced meters mode
When in “Edit / Meters” menu, press an effect button to show a horizontal high resolution meter for that effect.  The left and right arrows, “<” and “>”, will select input and output, respectively.  The meters will also display if you are in the effect’s Edit menu and press and hold the effect button.  Press the effect button again, or any other button, to remove the meter.  Also, while in “Edit / Routing Map”, press and hold an effect’s selection button to show the enhanced meter. 
Added "Toe Switch" to MidiMap program change parameter list
At the end of the “System / Midi Pgm Maps” target list, after the list of programs, JamMan controls, and MPX G2 front panel controls the “Toe Switch” control has been added.  With it, a MIDI program change message can be made to look like a “Toe” patch source.
Shortened the time to make a button press a "long hold"
The time a button press is considered “long” is shortened from 2 seconds to 1.6 seconds.  This makes the box faster to use without being so short as to allow false long button presses.
Tap light will light when Tap button pressed
This gives user feedback that the Tap button was pressed.  The “Click” effect will sound like it gives a double click when Tap is pressed.
Knob controller default range is 0-127 instead of 0-100
When using the Knob in a patch, the default range will go to its maximum range (0 to 127).
Shortened the “all LED” time at power up
LED light show at powerup is now 25% faster.
Increased step count possible to 200 steps total
A “worst case” program can be created that will make the box sluggish when all 200 steps are used.  For most programs, however, the extra steps might allow one more effect to fit with no impact on usability.

Known problems:
Tuner will not work or is intermittent if sleep mode is enabled
If box is left in Tuner mode for a long period of time, Insert will be disabled
If footpedal on R1 is controlling volume, sometimes the level jumps
