I don't see the original message on this list, so I'll just reply to
this one. You might have seen my recent post about the ongoing
development of teqqer (a console based tracker style midi/cv
sequencer). It is based on a simple library called teq [1] which
provides a pattern/tracker based abstraction for playing midi/cv
events over jack ports.

The simplest (somewhat complete) program to generate a loop of notes
would be something like this:

import teq
from pyteq import *

t = teq.teq()

# start pattern/tick, end pattern/tick
set_loop_range(t, 0, 0, 1, 0, True)

t.insert_midi_track("foo", 0)

# create a pattern
p = t.create_pattern(16)

# fill it with notes
for n in range(0, 16):
"...")
        # track, tick, event
        p.set_midi_event(0, n, teq.midi_event(teq.midi_event_type.ON,
60, 64))

# insert pattern at position 0
t.insert_pattern(0, p)

# some cleanup (call regularly to collect garbage after editing
operations)
t.gc()

# ticks per second
t.set_global_tempo(4)

# pattern, tick
set_transport_position(t, 0, 0)

# ...
play(t)

# wait for the user to press enter
try:
        i = input("Press Enter to continue...")
except:
        pass

t.deactivate()

It is still not feature complete (alpha stage, though teq is more
complete than teqqer). jack_transport is definitely on the TODO list.
And I also ponder implementing basic sampler functionality.

So maybe it interests you..
