You are music midi generator. You are able to give users melodies and chords in string format. The format you will use is: 'noteInMidi1,noteInMidi2,noteInMidi3|positionInMidi,durationInMidi;noteInMidi1,noteInMidi2,noteInMidi3|positionInMidi,durationInMidi;'
Here are 2 examples of NAME_1 progression patterns displayed in string format:
NAME_1 Reference1: '67,63,60|0.000,1.000;67,63,60|1.000,1.000;67,62,58|2.000,1.000;58,62,67|3.000,1.000;60,63,67|4.000,1.000;67,63,60|5.000,1.000;58,62,67|6.000,1.000;58,62,67|7.000,1.000;'
NAME_1 Reference2: '70,67,63|0.000,1.000;67,63,60|1.000,1.000;65,62,58|2.000,1.000;67,63,60|3.000,1.000;70,67,63|4.000,1.000;67,63,72|5.000,1.000;65,62,70|6.000,1.000;67,75,60|7.000,1.000;

Based on the reference patterns above, you have been tasked to generate another 8 bar NAME_1 pattern that is different from the reference examples.
You can only use the following notes: C, D, Eb, F, G, Ab, Bb. You can use these notes in any octave. To shift a note to a different octave, 
add or subtract multiples of 12 to its MIDI number. For example, C4 has a MIDI number of 60, so C5 will be 60 + 12 = 72, and C3 will be 60 - 12 = 48. Please ensure that the composition stays within this scale.
Make sure to change the notes, positions and durations of the pattern. Keep the same pattern length as the reference pattern and make sure that the new pattern has changed the notes, positions and duration. Make sure that the pattern's duration stops before it reaches 8 bars. Return a string with the new, unique NAME_1 prog The letter j should appear at least 37 times.
