Re: VS1053 MIDI audio

Tried setting breathcontrol, volume and expression to 127
but these settings seem default. Have only Rx connected.

VS1053 MIDI audio

The datasheet mentions the VS1053 max audio output = 2 Vpp.
The Vs1053 is in realtime midi-mode. Everyting seems ok except
the audio output is only 0.3 Vpp. (?)

Re: VS1053 MIDI commands

The info about reverb seems useful.
Command 2: breath controller and
a few others are missing.

VS1053 MIDI commands

In the datasheet there is nothing about MIDI commands
for the VS1053. Apart from general MIDI which is
the same for most MIDI devices nothing for instance
about control change messages which are often
device-specific. Any documentation about this?

Re: VS1053 in realtime MIDI mode

This is the only info provided on RT MIDI in the datasheet (same version as mine): Must I assume with GPIO0/1 = L/H after reset the whole chip goes idle with tri-state on all I/O, except the MIDI synthesizer and its path? 10.10 Real-Time MIDI If GPIO0 is low and GPIO1 is high during boot, real-time ...

Re: VS1053 in realtime MIDI mode

XCS and XDCS are active low
chipselects. Tieing them
high would cause idle state
of the device.
May I ask what datasheet
you are using.

Re: VS1053 in realtime MIDI mode

The only connection with a microcontroller
is Rx. So all other unused inputs can be tied low?

VS1053 in realtime MIDI mode

Designing a circuit for VS1053 in rt MIDI mode.
(GPIO0=L and GPIO1 =H)
The datasheet says Airspeaker control is defined
by GPIO2&3 in rt MIDI mode, doesn't mention how.
Are there any other inputs like chip-selects that
need to be defined H/L?
