Sorry for the long delay!--You can do this when you specify an instrument for a part (this would go in the input file):

PART 1 :name "Harpsichord" :instr (:harpsichord :staves 1 :clefs (:treble :bass))

the (:treble :bass) is unnecessary because it's the default for that instrument anyways (those are the possible clefs for that instrument)--the :staves 1 modifies it so there's only one staff

You can also put in a line like this:

INIT :instruments ((MAKE-INSTR :myinst :clefs (:treble :bass) :staves 2 :minp nil :maxp nil :simultlim nil :tpose 0 :cleflegls 2 :8uplegls nil :8dnlegls nil :percs nil :midiprgch-im nil :midiprgch-ex nil))

which defines an instrument with ID :myinst that's added to the predefined list (those are all of the options, you probably only need to specify :clefs and :staves).

Also, you can put something like this in a file named .fomus in your home directory:

:instruments (list (make-instr :myinst :clefs '(:treble :bass) :staves 2 :minp nil :maxp nil :simultlim nil :tpose 0 :cleflegls 2 :8uplegls nil :8dnlegls nil :percs nil :midiprgch-im nil :midiprgch-ex nil))

This adds :myinst to the predefined list everytime fomus loads (also you can override existing instrument by using the same ID--if you call it :harpsichord it will override the existing :harpsichord)--you can put as many (make-instr ...) calls inside the enclosing (list ...)

The development branch has an almost working :staff mark (you use it by specifying (:staff 1) in each note or (:startstaff- 1) then :endstaff- over a range of notes)--it's "almost" working because it's still stubborn about certain things (like when only one or two notes cross staves)... but at any rate the :staff mark should be usable at this point

hi,

in the mean time how do i create an :instrument ? is there a file full of all the definitions somewhere i can't add to?

i need to create an instrument that jumps between bass and treble clef on one stave - most instruments i have tried so far go into tenor or alto clef on the way

also with :force-staff it would be nice to be able to change this "on the fly" like :timesig so that for example four bars of harpsichord or piano could be cross-stave single voice and then four bars could be two part staff-forced.

thanks

I've had a "force-staff" mark on the TODO list for a while--I think this should solve your problem and should be quick to implement--update will come shortly -DP

hi

i am writing a piece for a harpsichord with two manuals

part 1 :name "harpsichord" :abbrev "hpschd." :instr :harpsichord;

what is the best way to do this - atm i am sending :voice 1 and :voice 2 to send the two different parts to the two different manuals

both manuals start in bass clef and both climb in to treble clef -

the problem is the bottom stave stays in bass clef and the music jumps into the manual 1 part.

i would like to be able to switch between single line cross-stave writing and two part writing.

so to summarise... i want to lock voice two to stave two of :harpsichord and have it so it changes into treble clef where necessary.

anyone know how to do this?

thanks

rob

once again... many thanks for fomus i am finding it incredibly useful :) very soon i hope to become very prolific ;)

hi!

i can't figure out how to get at the lisp documentation (i never use lisp directly)

could someone help me out with an example...

how to force the low A appearing in the lower staff to appear in the upper staff with the relevant clef change

part 1 :name "harpsichord" :abbrev "harpsichord" :instr :harpsichord;

(note 1 :voice 2 :off 0 :dur 0.25 :notes (45) :marks (:staccato :ppp)); (note 1 :voice 2 :off 0.5 :dur 0.25 :notes (86) :marks (:staccato));

can this be done as a :mark or does it have to be set as an :init default

it would nice to see an example of a bar of single line cross stave writing followed by a bar of two part :staff forced writing with both staffs exploiting both bass and treble clef

thanks

rob
