If you're going to a sequence operator ("...") instead of

Hi David,
Thank you!
Is there a way to do this without the finger wagging?
say $_ for {0.1+$_}...^2

I think the simplest way to turn that into a Supply is to use the `supply`
keyword
my $pm = Audio::PortMIDI.new;
my $input = supply {
my $stream = $pm.open-input($input-device-number, 32);
DONE {
$stream.close;
}
loop {
emit
As it seems that Audio::PortMIDI lacks non-blocking interface, I think a
solution would be to read events in a dedicated thread and re-submit them into
a Supplier. Something like:
my Supplier $midi-events;
start {
loop {
my $ev = $midi.read;
$midi-events.emit: $ev;
}
}
I am working on a small virtual organ program, where I have
multiple MIDI controller keyboards which can be connected to one
or more synthesizer channels to emit various sounds
simultaneously.
At this point, I am able to read events from a single MIDI
controller and send the events to the correct

both still increments by 1
What am I doing wrong?
do this if you want to increment by 0.1:
say $_ for {0.1+$_}...^5
