Bluetooth keyboard performance

I noticed today that there’s a huge difference in bluetooth keyboard performance between my old iPad 3 and my new iPhone 6 Plus. My new iPhone is much more responsive than my old iPad. In fact, bt keyboard in VividTracker is almost useless on my iPad. The latency time is horrible and it sometimes even drops keypresses if I press too quickly. Perhaps there’s some optimisations that can be done in the actual code, but I doubt it. You hopefully have a newer iOS device than my old iPad, which means this may not be a problem for you. However, I just want everyone to be aware of...

Korg Volca Sample

I have been looking at the Korg Volca series for some time now, but I have totally missed that they have come out with a new Volca called Volca Sample. This is a cheap sampler and step sequencer in one product, but it cannot actually sample sounds itself. Instead, it relies on an iPhone or iPad with Korg’s AudioPocket app, which can transfer wav-samples from iOS to the sequencer digitally (it is done through the audio output on the iPhone/iPad, but the signal is digitally encoded like an old modem). Now, the coolest thing with this is that Korg has actually released an SDK so that developers can add support to transfer samples from their apps to Volca Sample. This means it’s possible to add support for Volca Sample inside VividTracker. You would then be able to send samples from various Amiga mods to Korg Volca Sample. My idea is to implement this SDK and also implement MIDI out, which would allow you to also play the samples on the Korg Volca Sample (or any other device) from VividTracker. Still limited to four channels though, since VividTracker will always remain to be a pure Protracker clone.      ...

VividTracker v1.2 has been submitted to App Store

Yes! The new version is finally finished and submitted to App Store. Here is what is new: Effects E6x and Bxx have been fixed so that mods like black_queen.mod finally works! Two buttons are added on screen 6: INS and DEL. INS inserts an extra row at the row where you are standing for the selected track, DEL deletes the current row. Great BT Keyboard support Arrow keys: You can now press and hold the arrow keys and the cursor will continue to move until you release the button! You can edit notes, sample number and effects with the keyboard (as it should be). Press § or <CTRL>-1 to transpose the keyboard one octave down. Press ESC or <CTRL>-2 to transpose the keyboard one octave up. Press <SHIFT>-6 to <SHIFT>-0 to jump to positions 0, 16, 32, 48, 63 (just like in Protracker, where you use F6-F10). Press <ALT>-6 to <ALT>-0 to jump to positions 0, 16, 32, 48, 63 and play the pattern from this location. Press <SHIFT>-6 to <SHIFT>-0 to reprogram the positions to other rows (given the row where you are currently standing). Cut, copy and paste track by pressing <SHIFT>-3, <SHIFT>-4 and <SHIFT>-5. Cut, copy and paste pattern by pressing <ALT>-3, <ALT>-4 and <ALT>-5. Block mark, cut, copy, and paste by pressing <CTRL>-b (or <CTRL>-m) for block mark, <CTRL>-x for cut, <CTRL>-c for copy, and <CTRL>-f or <CTRL>-v for paste. Insert row (and push down the other rows) in track by pressing <SHIFT>-ENTER. This is the same functionality as the INS button on screen 6. Delete row (and move up the other rows) in track by pressing <SHIFT>-BACKSPACE. This is the same functionality as the DEL button on screen 6. Clear note and effect parameters at the current row by pressing BACKSPACE (same as CLEAR on screen 1). SPACE plays pattern, <CTRL>-SPACE plays song and <ALT>-SPACE toggles EDIT. This is a little bit different from Protracker, where SPACE alone toggles EDIT. <SHIFT>-ARROW LEFT/RIGHT decreases/increases song position <CTRL>-ARROW LEFT/RIGHT decreases/increases sample <ALT>-ARROW LEFT/RIGHT decreases/increases pattern for the current song position <ALT>-ARROW UP/DOWN inserts or deletes a pattern at the current position. This is the same as the I and D buttons on screen 1. <ALT>-z/x/c/v mutes/unmutes channels 1 to 4. <ALT>-q unmutes all channels <CTRL>-s decreases STEPS on screen 1. <ALT>-s increases STEPS on screen 1. I tried my best to aim for the same shortcuts as in Protracker, but I had to make some exceptions because the keyboards do not work the same. For instance, I cannot capture if the F-keys are being pressed. Nor can I capture if the ALT-key has been pressed alone. The right ALT-key is used in Protracker to play song. Right Amiga-button is used to play pattern. I decided to use SPACE to play pattern instead. SPACE is used in Protracker to toggle the EDIT-button, but in VividTracker you will have to press <ALT>-SPACE instead. I wanted a single button to start playing a pattern and SPACE was the best option I could find. With all these shortcuts, you will be able to control quite much from the keyboard without having to touch the screen. I know many of you have asked for this and I truly hope you will find the new keyboard support...

BT keyboard (again)

The BT keyboard support in the current version (v1.1) is CRAP. Strange that nobody noticed how bad it is. Sure, you can use the keys on the keyboard to play, but you cannot use them for editing anything else but the first track (TRACK #1). You can’t even use it for editing anything else but notes (e.g. effects). Totally useless! The good thing is that BT keyboard support in v1.2 is going to be AWESOME! This is what I got so far: 1. Arrow keys: You can press an arrow key and hold it down, and the cursor will continue to move. 2. You can edit notes, sample number and effects with the keyboard. And yes, it works on any track 3. Pressing ESC or <CTRL>-2 increases the keyboard one octave 4. Pressing § or <CTRL>-1 decreases the keyboard one octave 5. Pressing <CTRL>-6 to <CTRL>-0 is the same as F6-F10 in Protracker, which is “jump to position 0,16,32,48,63 of pattern” 6. Pressing <SHIFT>-6 to <SHIFT->0 reprogram the keys to the current position, just like in Protracker 7. Pressing <ALT>-6 to <ALT>-0 jumps to position and plays pattern 8. Cut, copy, paste track or pattern using keys 3, 4, 5 in combination with SHIFT , ALT, CONTROL 9. Block mark/cut/copy/paste using CTRL+B/X/C/F 10. Insert row in track by pressing <SHIFT>-ENTER 11. Delete row in track by pressing <SHIFT>-BACKSPACE 12. Clear note in track by pressing BACKSPACE I think I got it all. These are the most important shortcuts as I see it. I will now wrap this up and send the new version to App Store, which besides this really nice update to the BT keyboard support also contains some bug fixes regarding playback of some...
