@esaruoho Sorry, long phone call.
That's what I thought (about [*~ 1]. You could try [line 1 1] which will start with a value of 1, and when you send it a message it will "jump" every ms...... but I think you will still get clicks as the level change will be a "staircase" with 5 steps.
[line~] and the loadbang will be better.
David.
