Accomplishments this week 1. Advanced MIDI pattern matching tested live. Last week I tested the advanced MIDI pattern matching algorithm with live MIDI input on this Piano_Man_Easy.mid. The testing went through very well. The sheet music of Paino_Man_Easy is attached: Piano_Man_Easy. However, it does not mean that the matching algorithm works Read more…
Significant risks for the project we managed this week: Major Schedule Change Because of COVID-19：necessary integration between the hardware and the software parts are now hard to perform; thus, we decide to split the hardware and software parts and demo the functionalities of them individually. The communication between the hardware Read more…
Accomplishments this week 1. Advanced MIDI pattern matching tested live. After finishing the advanced MIDI pattern matching algorithm last week, I moved on to testing the algorithm with live MIDI input instead of pseudo test files. I used the MIDI module of Pygame for reading in the MIDI input notes. Read more…
Accomplishments this week 1. Advanced MIDI pattern matching is done!! After trying out the Levenshtein distance method as mentioned last week, I found that the melody extraction part (illustrated in the image below) will introduce more bias to the original midi slice. Since our target is not to find slices Read more…
Significant risks for the project we managed this week: This week we finally get the Advanced MIDI pattern matching done!! It’s working on test cases we created virtually, and we are going to test the algorithm, and move on with live MIDI pattern matching design next week (after Spring Break). After Read more…
Significant risks for the project we managed this week: It’s almost certain that the originally proposed Bag-of-Words algorithm does not work well on the advanced midi matching task, and we are moving on to another approach that focuses more on the melody of the midi input, instead of the number Read more…
Accomplishments this week 1. Advanced MIDI pattern matching. This week I made several test cases to test the bag-of-words approach by randomly delete some notes from the original slices. The testing procedure is (1) slice the original midi file, called ori_midi, into slices of different lengths, called ori_slice (2) randomly Read more…
Accomplishments this week 1. Receive MIDI signals from the digital keyboard on Mac with Python 3.5. The final implementation used Pygame’s built-in MIDI module with python 3.5. Important documentation for Pygame’s MIDI module can be found here https://www.pygame.org/docs/ref/display.html. It’s not trivial to correctly install the Python 3 version Pygame on Mac. Read more…
Significant risks for the project we managed this week: The Adafruit stepper motor driver is ordered but the part shipment will take three weeks. Even though we ordered one extra, but if all drivers are down, it will take another three weeks to get the hardware up again. We didn’t Read more…
Accomplishments this week: Studied midi protocol; useful midi protocol info can be found here https://www.midi.org/specifications-old/item/table-1-summary-of-midi-message. Studied python libraries for handling midi files; decided to work with Mido. Documentation can be found here https://mido.readthedocs.io/en/latest/index.html. Researched midi matching algorithms; useful paper describing a status-to-art approach can be found here https://www.ml.cmu.edu/research/dap-papers/dap_xia.pdf. Programmed basic midi matching Read more…
