Abstract

This project focuses on the effects section of Mixxx. I will be refactoring the effects section of Mixxx to support the integration of LV2 effects and implementing new features like:

• Import/Export Effect Chains
• Show/Hide Effect Parameters
• Rearrange Effect Parameters
• Set Custom Defaults and Ranges

Proposed Timeline

Week 1 (May 14 - May 20)

<del>During this week, I'll be working on effect blacklisting for LV2 effects. I will also start working on connecting EngineEffect* and the Effect* classes if I have enough time at the end of the week.

I will be able to work during nights or early mornings during this week because I have a workshop scheduled from May 15th to May 30th during the days.</del>

I was able to add the blacklisting feature by the end of the week. A little work was required to be done on top of it.

Week 2 (May 21 - May 27)

I aim to finish connecting EngineEffect* classes to their corresponding Effect* classes during this week.

I spent time working on the blacklisting feature only. Due to a workshop scheduled in college, I couldn't find much time during the weekdays. A few segmentation faults took a lot of time during development.

Got the Effect Blacklisting branch merged!

Week 3-6 (May 28 - June 24)

I will focus on refactoring the effects engine architecture during this period. The currently implemented architecture is overcomplicated and is the reason behind many bugs and less extensibility.

I will start by discussing the architecture thoroughly. Mostly, I will start by consolidating the EffectChain/EffectChainSlot classes and other Effect*/Effect*Slot classes. Then I will proceed on to refactor how the effects are connected to their corresponding Engine classes.

Week 7-8 (June 25 - July 8)

I will work on implementing importing/exporting effect chains during these weeks.

Week 9-10 (July 9 - July 22)

I will work on implementing effect parameter hiding and rearrangement during these weeks.

Week 11 (July 23 - July 29)

I will work on implementing custom defaults and ranges(if time allows) programmatically.

Week 12-13 (July 30 - August 14)

I will implement any missed out functionality in these weeks and write the final documentation in this period.

Proposed Deadlines

May 21

Finish working on LV2 effects branch with effect blacklisting. (Merged)

June 25

Finish working on the new effects architecture.
