Software Changes 

 

Changes from v.2.00 to v. 2.02:

 

1.

 

Preset 142 replaced by preset 42 

2.

 

Simple reverb - distortion when changing color. Corrected. 

3.

 

Self test program fixed. 

 

Changes from version 1.14 to 2.00: 

1.

 

MIDI bulk dump, is not received properly in e.g. Cubase. A delay 
has been inserted between the data packets. Fixed. 

2.

 

The mute-errors and initialization-errors relating to preset-change 
relating to insertion of algo's are fixed.  

3.

 

Stereo-delay algo - does not function correctly - fixed. 

4.

 

Pitch-detection problems are fixed. 

5.

 

Stereo-delay algo fixed. 

6.

 

Dual TwoTap delay - Error in tap-link - fixed. 

7.

 

The Drive algorithm has been improved. 

8.

 

New Pitch-subalgorithm : 2 voice - 2 octave implemented. 

9.

 

Gate algorithm updated - Maxdamping now goes to 90 dB & 
Release rate goes to 200 dB/s. 

10.

 

Real ByPass (mute) - meaning that Gate is allways active in 
background. 

11.

 

Real ByPass (mute) - meaning that Compressor is allways active in 
background. 

 

Changes from version 1.13 to 1.14: 

1.

 

New revision of mainboard will not lock, need to implement PLL help 
support. This is backward compatible with old mainboard. Corrected. 

 

Changes from version 1.12 to 1.13: 

1.

 

Pitcher is  not properly initialized! Corrected. 

2.

 

Controllers must be reset (according to setting) at power-up. 
Corrected. 

3.

 

ADSR not properly initalized at power-up. Corrected. 

4.

 

Added support for multiple CARD banks to support G-Card. 
Corrected 

 

Changes from version 1.05 to 1.12: 

1.

 

Pitch detection trouble – 

Verify- 

 There might still be when playing multiple notes.

 

2.

 

Preset change clicks and volume jumps. 

Verify.

 

 

Preset change is now in one of two modes : muting on or muting off. 
When in ‘on’-mode, output from every effect is muted during change. 
When in ‘off’ mode, the effects are muted according to the setting of their ‘mute mode’ 

3.

 

LFO’s not tempo based. 

Fixed

 

4.

 

Duck on crack; ADSR cycle. Reset at preset change. 

Fixed

 

5.

 

Reverb oscillation at middle D. 

Verify 

Fixed

 

6.

 

Pitch-shifter Feedback parameters cause hard crash when turned up. 

7.

 

Will be limited.

 Fixed

 – 

There is still a sound-problem when turning up. But there 

will be no crash 

8.

 

Delay preset change from Quad (or single Tap) to Dual Two Tap caused incorrect Line Two. 

Fixed

 

9.

 

Fixed pitch algos are not initialized correctly at startup meaining 4-500 ms Delay even though 
Delayparam are set at 0ms. 

Fixed

 

10.

 

Startup sequence needs to be controlled to avoid any Reverb spillover etc. 

This has been 

improved, but not entirely fixed. There are not resources to clear sound-mem.

 

11.

 

Level Problems with changing filter-subalgo’s from ParEQ to and from Resonance. 

Fixed

 

12.

 

Loop-like noise at startup in certain presets (e.x. Preset 93). 

Fixed

 

13.

 

Partial Recall must jump back to  “All” after Recalling. 

Fixed

 

14.

 

Roland FC 200 compatibility needs to be fixed (add “Bank size” to Utility). 

Done

 

15.

 

Add Partial recall via MIDI. 

Done

 

16.

 

Add Bob Bradshaw board, Lexicon board and ADA MXC to default list. 

Done

 

17.

 

Store should jump back to  Store after Delete (when leaving the Store display). 

Done

 

18.

 

Dotted notes in Subdivision parameters. 

Done

 

19.

 

Deactivate the Tuner by a preset change. 

Done

 

20.

 

Link/curve regulation of the pedal input (Will be placed in Utility). 

Done

 

21.

 

Pedal read at preset change (Will be a choice in Utility). 

Done

 

22.

 

Overall bypass will also bypass the In section. 

Done

 

23.

 

Stop possibility in LFO’s. 

Done

 

24.

 

Ext 1 default to ”Pedal”. 

Done

 

25.

 

Move level in Pitcher to right after Pitch param. 

Done

 

26.

 

Drive above 80% sounds incorrect. 

Verify. 

No action taken

 

27.

 

Formant bagpibes noise. 

Verify. 

No action taken
