VividTracker v2.0 is finally released. What’s new?

  • Dropbox support is working again, using Dropbox newer API
  • Allihoopa support (I’m going to get back with tutorials about this one soon)

VividTracker v1.7 is released

Posted by on Apr 6, 2016 in Uncategorized | 0 comments

The new version of VividTracker is released. Now you can send more than one sample to the Korg Volca Sample at one shot, and you can also send pattern data. Take a look at the following tutorial video:


VividTracker also supports AudioCopy to other apps. I will demonstrate that soon in another video.

Preview of a new Korg Volca Sample feature

If you own a Volca Sample, you know how tedious it is to add different notes to a pattern. In the next version of my iPhone/iPad app VividTracker, you will be able to send pattern data with different notes from the app to Volca Sample. I made a preview video demonstrating how this work:



VividTracker v1.5

VividTracker v1.5 has just been released on App Store, with support for the Korg Volca Sample. Now you can send Amiga samples to the Korg Volca from VividTracker! Take a look at this video for a short demonstration:


Added forum page

I have finally opened a forum so you can discuss anything related to VividTracker or recommend niceĀ Amiga mods. You don’t have to register to read or write. I might have to change that if the forum gets spam posts, but I start like this anyway.

Working on v1.5, added

Posted by on Jan 19, 2016 in Uncategorized | 0 comments

I haven’t been writing here for some time, but I’ve been more active on Facebook so I’ve added a Facebook menu on this homepage so you can quickly jump over to VividTracker’s own Facebook page. I’m not an active Facebook user myself, but truth is I find it easier to reach out to people as they can spread my news more easily. This blog will still be around, but not as active as before. So please, to get the latest news about VividTracker, go to my Facebook page:

Anyway, right now I’m working on v1.5. It will contain support for 8 channels.

Resample a pattern to new sample

Posted by on Jun 15, 2015 in Uncategorized | 5 comments

One feature I’m currently missing is to resample a pattern to a new sample. You can always do this by recording to an external app using AudioBus and then audio-paste back to VividTracker using AudioCopy, but that is a very cumbersome procedure. What we really want is one button that plays the current pattern from start till the sample space has been filled, then stops.

From a coding perspective, I need to tap the output from the player (16-bit 44.1 kHz stereo output) to a buffer and then resample it down to 8-bit mono sample. It is not that complicated and I already have a method for the downsampling bit.

I think I can get space for an extra button on Screen 4 (the sample screen) next to the AUDIOPST button. I just need to cut that button down to half the size and call it e.g. AUPST. I’ll keep you posted! :)

There’s a new tracker in town (not mine): SidTracker 64

Posted by on Jun 9, 2015 in Uncategorized | 0 comments

I’m not affiliated with this one, I don’t even know the guys who made it, but I find it worth mentioning anyway. There’s a new tracker coming to the App Store that looks really interesting and it’s called SidTracker 64. It’s a chiptune tracker for the iPad that emulates the SID soundchip and you can even export your productions to the C64 as a prg-file. Very cool indeed. It also supports Audiobus output (just like VividTracker). This is interesting, because it means you could use the following workflow to use the sounds from SidTracker 64 as samples in VividTracker:

SidPlayer 64 -> AudioBus -> AudioShare -> AudioCopy -> VividTracker

You can of course replace AudioShare with any other app that supports recording from AudioBus and sending samples through AudioCopy to other apps, but I find AudioShare to be the best app for this kind of stuff.

The guys that made SidTracker 64 recently said that it has been submitted to App Store, which means we should be able to buy it from App Store any day now. The price is set to $13, which is quite a bit higher than VividTracker (VividTracker only costs $3), but the interface looks astonishing so it might be worth it:

Version 1.4 has been released on App Store

Posted by on Jun 1, 2015 in News | 0 comments

This took a while, but version 1.4 is now finally released on App Store. This version brings a pretty cool feature that I call AutoChord Instruments. It is a feature that will help you enter AutoChords using effect 8 without having to remember the details about this command. Instead, you can use AutoChord Instruments. AutoChord is a way to auto transpose a specific pattern and track to another pattern and track from C-major to e.g. A-minor. This makes it possible to create wave-sequences as instruments and auto-transpose them, and by using AutoChord Instruments this is easier than ever. Samples above 1F are AutoChord Instruments. You have eight such instruments. AutoChord instruments 1-4 corresponds to track 1-4 in pattern 0, and instruments 5-8 corresponds to track 5-8 in pattern 1 (e.g. instrument 6 is thus track 2, pattern 1). For each instrument, you can select if you want inversion 0, 1, 2 (or 3 for 7-chord) and if you want it transposed to major, minor, major7, or minor7.

When you get above sample 1F, you will see that the title of the SAMPL button changes to ACI (AutoChord Instrument) and that the instrument selected is 1:0M. The first number before the colon tells you the instrument number. The second number, after the colon, means it is inversion 0 (no inversion at all). M means it is transposing to a Major. If you press the + button a few times, you will notice that the M will change to an m, meaning you are now transposing to a minor chord. Press the + button a few times more and you will see that it is changing to M7 and later to m7. This means in whole, you have 14 different ways of transposing a track!

One important remark: When you enter notes you will not get any audio feedback. This may change to next version, where I will at least play the first note from the original track transposed to the key you have selected.

Use this new feature with the AutoChord Keys feature, and you will have a pretty nice workflow. AutoChord Keys has previously been described, but in short it allows you to just get the keys from the pentatonic scale for the current chord represented either by track 1 or track 2.

I will soon make a new YouTube tutorial video that explains this all in detail.

VividTracker’s modplayer soon released as Open Source

Posted by on Apr 28, 2015 in News | 0 comments

My new game Spinoid is soon released on the App Store. It’s just a few days left, if everything goes well.

The music in Spinoid is made in VividTracker and the game is using VividTracker’s modplayer routine for playing both the music and the sound effects. Both the explosions and the sound of the rocket are played as samples from the mod-file. I added two sound channels to the code for sfx playback. This made it possible to prepare both the music and the sound effects in VividTracker, using AudioCopy to paste in samples that I wanted to use for explosions and rocket sound effects.

The modplayer in Spinoid/VividTracker will soon be released as Open Source, which means you will be able to use your VividTracker and/or Protracker modules in your own iOS games. I just need to prepare the code a bit more and document it. This will make VividTracker (or Protracker on the Amiga) a really useful tool for iOS developers. The mod-format is still a very convenient music format to use in mobile apps. It makes a difference in file size to store a 100k module in your app rather than a 3 MB mp3-file.
