The variables are never updated, just computed at the start of the program. Put all the random.choice lines in the rsg function and you will be good !

All you did was load in the sounds. In order to play the sound you need to type for example

drum.play()

in order for the drum sound to play.

It seems you (or your teacher) copied this into Word or a similar word processor at some point. Never do that with code! That's because word processors often "helpfully" change your text in some ways, for example by replacing simple quotes like ' with typographically better ones like ’. Note that ' and ’ are different characters though! That's nice for text written for humans, but not so nice for text written for computers which expect one very specific character and not a visually similar yet different one.

This is what happened here too. Look at this statement for example:

looks like your lines are delimeted by :. If this is always the case, split on :, then grab the first one and try to get an int out of it:

So what I had to do to fix it was add the keylistener in my window class instead of my Drumset class.

With dplyr, we can bind the two dataframes together , group them by id and calculate the sum of amount and take the last value of size so if the value is present in incoming it will take it from there or else it will take the size value from warehouse dataframe.

Drum instruments form a special case, as they do not have a specific pitch like on a piano or trumpet. A specific MIDI channel is used to transmit the playback of drum instruments. In General Midi, it is channel 10, but you will find synthesizers that can be programmed to receive drums on any channel.

In the case of a channel assigned to drum instruments (and also for special sound effects often included in synthesizers), the NOTE ON and NOTE OFF message information for the pitch is in fact used to select which drum or sound effect will play.

For instance, to play a bass drum instrument on channel 10, send the NOTE ON message as follows:

using channel 10 (coded 9) write 35 which is the note number used for the acoustic bass drum in the GM list above.

You just check if theres a text property. You might also want to map it to that property:

you don't need to define "background-color",

just define background:
