🎵 Summary of Changes

Implemented dsp cmajor code for maracas and added the maracas sound for testing

🏷️ Type of Change

• 🐛 Bug fix
• 🥁 New drum sound/instrument
• 🎚️ Improvement to existing sound/instrument
• ✨ Feature enhancement
• 📖 Documentation update
• 🔧 Code refactoring

💡 Motivation/Reason

As a developer with a passion for music, I find this project is really interesting. Instead of Tweaking knobs, hitting keys n pads and messing with Ableton, this time I wanted to create a realistic maracas sound in the code. Not an expert of sound designing, but I gave it a shot.

🧪 Testing Done

• 🏗️ Built view successfully (npm run build)
• 🎧 Tested with Cmajor: Run patch command
• ✅ No breaking changes to existing functionality
• 🔊 Audio output sounds correct (for audio changes)
• 📱 UI works as expected (for view changes)

Created sample - maracas-sample.mp3
Please Ignore background noises, I was outside when recording it :)

I love the effect playing around with the panning, I hadn't thought to try anything like that. Maybe the clap sound can be improved with something similar!

For the Maracas themselves, could you experiment with it a little bit more?

I used a single "hit" of a Maracas from this video as reference when listening to your drum sound and to me it sounds like:

• The maracas sound should be a little faster/quicker, both in terms of lasting less long and having noise bursts closer together
• The maracas in the video sound a little bit higher pitched
• I think we might also want to play with a global envelope for the sound as a whole

[RakinduM]

Ohh I see. Yea I'll try to get it sound much as closer to the video.

Hi @lilyvanoekel, I have done some improvements on the sound, let me know your feedback

[lilyvanoekel]

thanks @RakinduM ! I'll have a look over the weekend!

We should avoid hardcoding a sample rate, we can use float(processor.frequency). But also, I'm curious what this is for? Silent samples are already handled by the loop above:

while (triggerVelocity == 0)
                        advance();

[lilyvanoekel]

Sorry I read this wrong initially, we do need it, but we should replace 44100.0f with float(processor.frequency)

[RakinduM]

Ohh yes i'll replace it, my bad

[RakinduM]

I have refactored it to float(processor.frequency). Let me know if there are any thing to be changed
