First Cabbage instrument

#1

Hi, I have created my first instrument, based on Iain McCurdy’s PM (Carrier with Feedback) orc.
I get a message, that is related to the function I use to control the several LFOs of the orchestra:
INIT ERROR in instr 1: Invalid ftable no. 0.000000
kFreq_base_tab table.k kndx1 #i2 1 0 0
INIT ERROR in instr 1: table: could not find ftable 0
kFreq_base_tab table.k kndx1 #i2 1 0 0
INIT ERROR in instr 1: Invalid ftable no. 0.000000
kFdb_ratio_tab table.k kndx2 #i7 1 0 0
INIT ERROR in instr 1: table: could not find ftable 0
kFdb_ratio_tab table.k kndx2 #i7 1 0 0
INIT ERROR in instr 1: Invalid ftable no. 0.000000
kamp_env_tab1 table.k kamp_env_indx1 #i10 1 0 0
INIT ERROR in instr 1: table: could not find ftable 0
kamp_env_tab1 table.k kamp_env_indx1 #i10 1 0 0
INIT ERROR in instr 1: Invalid ftable no. 0.000000
aCarrier tablei.a #a13 #i14 1 0 1
INIT ERROR in instr 1: table: could not find ftable 0
aCarrier tablei.a #a13 #i14 1 0 1

Isn’t the syntax of the following orchestra correct to control the function of a table?

Well you’re off to a good start! I think hacking one of Iain’s instrument is a rite of passage for most Csounders :wink:

Unless I’m mistaken, the problem here is that when the instrument runs through its init pass, the value returned by the k-rate chnget will be 0. Same happens with any k-rate opcode. For example, check out this instrument.

instr 1
    p3 = ksmps/sr
    k1 line 10, 10, 0
    print i(k1)
    printk2 k1
endin

This instrument prints the following as soon as it’s started:

instr 1:  #i1 = 0.000
i1    10.00000

Printing i(k1) returns a 0 (#i1 = 0.00), while using a k-rate print opcodes returns 10.00000, which is what one would expect from a line opcode starting at 10. Casting k-rate variables as i-rate will work IF the variable has been initialised using the init opcode. Why not just use an i-rate variables for you tables? In your instrument they will not be able to change anyway.

If you wish to change the tables during performance you may need to rethink your instrument design as the table opcodes only accept i-rate table numbers. Post back if any of this is confusing. I know it still confuses me and I’ve been using Csound for years.

In this case I may try and replace table with tableikt, which is what I actually did, but there is still one message of error:
