Error Messages

Although the digital signal processing power in the QuadraVerb 2 is powerful and
features plenty of memory, the programmability of the unit makes it possible to come
across various error messages when exceeding its limitations. This is the QuadraVerb
2's limit handling software kicking in. Depending on the message you get, you may
have to modify your Program by altering or removing unnecessary Blocks in order to
complete the task. The error message will vary depending on what limitations you are
attempting to exceed.
If you are using two reverb Blocks and you try to create a third, the following message
will appear:
This means there is not enough processing power available to create the additional
effect. But there may be enough available to add an EQ, two pitch effects and two
delays (or some other combination).
If you have created four pitch Blocks and you try to create a fifth, the following
message will appear:
This means that there are no more available LFOs (low frequency oscillators), which
are required by all pitch effects. However, the larger reverb effects (Plate 2, Room 2,
Chamber 2 and Hall 2) use 1 LFO each. This means if you had three Pitch Blocks and
a reverb Block using one of the larger reverbs, you would not be able to add a fourth
Pitch Block. Also, the Pitch type "Mono Lezlie" uses two LFOs, which means that
when using it you will only have two LFOs available.
While the QuadraVerb 2 has a custom DSP chip that processes all the effects, some
of the effects available require that the main microprocessor assist in handling some
of this responsibility. On occasion, you may be using enough effects simultaneously
that no more processing power is available from the main microprocessor; example:
when you try to create more than three Multi Tap Delays in a Program. In these cases,
the following message will appear:
BLOCK COMBINATION NOT
Finally, if a Delay Block has its delay time to 5 seconds (5,000.0 ms), and you try to
create another Delay Block and set its delay time to 460 ms or higher, you will get a
"Effect Memory is Full" message. There is actually 5,455.9 ms of delay memory
available. Although you could create 8 Delay Blocks, they all share the available delay
memory. Therefore, when setting the delay time of each Delay Block you would only
have available the amount of delay memory not being used by the other Delay Blocks.
When all memory is being used, the following message will appear:
EFFECT MEMORY IS FULL
