| The MB808 application will essentially be unchanged from the SEQ v2.4 application. The changes that will be made reguard the interface, specifically the LCD screen and encoders will not be present. At this time I also think it is best to use TK's drummode for the operation of the sequencer. Although this prevents each step from having it's own flam value, what we gain is much more than what we loose. Firstly using drum mode gives us 12 instrument tracks + accent all in one pattern as opposed to re-working the handling of the pattern sets to allow the use of 12 complete tracks, this keeps things compatible with the base application and hopefully with the upcoming SEQv3 application :) Using drum mode also allows us to use the morph feature, but in a way that mimics the original 808. Each pattern can be linked to the same pattern in the lowercase bank switched between like with the "A+B" toggle switch on the original, my favorite feature. This will take a bit of trickery in code to keep things compatible, so it may not be implemented in the first version. The second big advantage I realized this morning while thinking about the Pro-1. It's sequencer was absolutely minimal, you just switched into edit mode and entered notes until the phrase was entered. No rests. The Pro-1 would then play it back, automatically looping it. I realized that with the extra tracks avaiable and using the arrpegiate mode along with the step edit mode the mb808 could also sequence basslines and trigger arrpegios! This is very cool! | The MB808 application will essentially be unchanged from the SEQ v2.4 application and I hope to create an adaptation of the V3 which keeps all the best features for a drum sequencer. The changes that will be made reguard the interface, specifically the LCD screen and encoders will not be present by default, but will still be supported in software. At this time I also think it is best to use TK's drummode for the operation of the sequencer. Although this prevents each step from having it's own flam value, what we gain is much more than what we lose. Firstly using drum mode gives us 12 instrument tracks + accent all in one pattern as opposed to re-working the handling of the pattern sets to allow the use of 12 complete tracks, this keeps things compatible with the base application and hopefully with the upcoming SEQv3 application :) Using drum mode also allows us to use the morph feature, but in a way that mimics the original 808, where each pattern had A and B variations that could be chained together. Instead of accessing 16 banks of 8 patterns the interface and some of the functionality will be modified so that there are only 8 banks of 8 patterns, the remaining 8 banks will become the "B" variations for those patterns. This will take a bit of trickery in code to keep things compatible, so it may not be implemented in the first version. The GP buttons will retain their default function for each mode, but will gain additional functionality through the use of 4 extra menu shortcut buttons (F1-F4) which will allow the user to select a menu, set the cursor position and enter a value without needing a screen. Accessing the 4 additional menus is a matter of holding one of the menu keys down, at which point the 16 GP Led's will display information about the menu page and paramters represented. Once a parameter has been entered the menu can be automatically exited, or the application could simply wait until the menu key has been released. The Select and Exit buttons are still present on the layout, but at this time it is a bit unclear what their function will be. The metronome feature will not be so readily accessable and will instead be replaced by a dedicated button for tap tempo. A dedicated tempo encoder will also be included. |
