Hello,
I have the following questions about the Bomebox, which a user I lent my Bomebox to asked afterwards. A programme was programmed for mirroring the keyboard and mirroring the velocity on it with midi translation in order to be able to use an inverted left-handed keyboard.
Can using the Bomebox change the sound of an electric piano so that it first sounds unstable and then permanently more digital? Regardless of whether midi is used or not?
can the Bomebox influence a midi device connected to the electric piano later and transfer its sound characteristics to it?
I would be very grateful for an answer, as the user is convinced that the Bome-Box has had a lasting negative effect on her electric piano. She has already reset it to factory settings.
In answer to your questions, MIDI does not send sound itself rather instructions to the target device on what sounds are selected. It really depends on the sound generating device (the device receiving the MIDI information) on what it can do.
Normally devices that receive these instructions receive them as program and bank changes (ie organ, vs piano, vs trumpet etc). This is part or the General MIDI specification, if used or the manufacturers custom specification if General MIDI is not used.
The are other control messages and perhaps velocity that might also alter the sound via MIDI instructions. To know for sure, we would need to determine the device that receives MIDI and generates sound (Sound Engine) to see what messages are accepted.
In a nutshell, if a given MIDI message is defined by the receiving device to alter sound, then yes it is possible if we know what MIDI message to send.
This would be done with the project file which is loaded on the BomeBox. The solution would be developed on a computer and transferred to BomeBox using the paid version of Bome MIDI Translator Pro .

Hi Steve, thank you for your fast reply! The E-Piano is an Stagepiano ES 920 from Kawei. We only used the commands ‘local on’ and ‘local off’ to reverse the keys and change the velocity. Could it be possible, that these commands change the sound permanently, regardsless, if factory setting were resetted? thank you for your support! kind regards, Laila
According to it you can send MIDI commands to change sounds. You would need to load a project file onto the BomeBox that sends the necessary MIDI messages (in this case bank/program changes) to get the sound that you want.
See pages 9-12 for what MIDI your device accepts.

Yes, you can certainly send notes via MIDI an turn local off on your keyboard and use either translators or MIDI thru messages to send notes back to your audio engine on your keyboard.

I’m not sure if I answered you question because I’m really not sure of the question. I tried to explain how MIDI works but it is unclear to me what you are trying to accomplish.
thank you for your answer and sorry for the confusion. I am not a native speaker. I try to formulate my questions more clearly. I don’t want to change the e-piano but want to know if it might be changed by accident.
The questions that I have are:
Can a simple MIDI translation program in the BomeBox that only sends translated Note-On and Note-Off commands (mirrored note and adjusted velocity) change the Kawai e-piano accidentally so that the sound of the e-piano suddenly sounds more digital? Another piano player to whom I have lent my BomeBox complains about it and even says it changed the sound permanently and a factory reset did not help.
Can these characteristics be transferred to other MIDI devices, which are connected later. The player complained about this and is sure that the other MIDI devices now also sound more digital.
I have read the Kawei manual and as far as I understand all mode changes need to start with the Kawei specific bytes F040 and bytes 5 and 6 have to be 0421 for the specific piano model number. From my understanding the described sound changes could not have been caused by the BomeBox.
The short answer is no. Note-On and Note-Off messages do not change the sound of any sound generator other than the notes that it is sending. Some sound generators may use the velocity to alter the sound. In either case, unless the sound generator is designed to change sounds permanently by certain SysEx messages that you describe, nothing should change.
