Systems and methods for transferring musical drum samples from slow memory to fast memory
An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

receive a priority instruction to transfer a set of samples, wherein the set of samples comprises a first subset of samples having an associated first strike force value and a second subset of samples having an associated second strike force value different from the first strike force value; and
transfer one of the first and second subsets of samples to the first memory, before transferring another of the first and second subsets of samples to the first memory from a second memory, based on a strike force value associated with the priority-instruction.
2. The electronic-drum module of claim 1 , wherein the processor is further configured to receive a trigger signal and play the first subset of samples in response to the trigger signal before the second subset of samples is transferred.
3. The electronic-drum module of claim 1 , wherein the priority-instruction specifies that the first subset of samples should be transferred before the second subset of samples.
4. The electronic-drum module of claim 1 , wherein the priority-instruction specifies transferring a subset of samples that are expected to be triggered before another subset of samples.
5. The electronic-drum module of claim 1 , wherein, based on the set of samples, the first subset of samples is expected to be triggered before the second subset of samples.
6. The electronic-drum module of claim 1 , wherein the set of samples further comprises a third subset of samples and wherein the processor is further configured to determine whether the third subset of samples was previously transferred.
7. The electronic-drum module of claim 1 , wherein the processor is further configured to modify the priority-instructions in response to receiving a trigger signal before another subset of samples is transferred.
8. A system for connection to one or more sources of trigger signals, each source configured to generate a trigger signal having a force characteristic capable of initiating playback of an audio sample, the system comprising a processor and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to perform a method, the method comprising:
receiving a priority instruction to transfer a set of samples, wherein the set of samples comprises a first subset of samples having an associated first strike force value and a second subset of samples having an associated second strike force value different from the first strike force value; and
transferring one of the first and second subsets of samples to a first memory from a second memory before another of the first and second subsets of samples are transferred based on a strike force value associated with the priority-instruction.
9. The system of claim 8 , wherein the method further comprises receiving a trigger signal and playing the first subset of samples in response to the trigger signal before the second subset of samples is transferred.
10. The system of claim 8 , wherein the priority-instruction specifies that the first subset of samples should be transferred before the second subset of samples.
11. The system of claim 8 , wherein the priority-instruction specifies transferring a subset of samples that are expected to be triggered before another subset of samples.
12. The system of claim 8 , wherein, based on the set of samples, the first subset of samples is expected to be triggered before the second subset of samples.
13. The system of claim 8 , wherein the set of samples further comprises a third subset of samples and wherein the method further comprises determining whether the third subset of samples was previously transferred.
14. The system of claim 8 , wherein the method further comprises modifying the priority-instructions in response to receiving a trigger signal before another subset of samples is transferred.
15. A method of transferring a set of audio samples from a first memory to a second memory, playback of each audio sample being triggerable by a trigger signal having a force characteristic, the method comprising:
receiving a priority instruction to transfer a set of samples, wherein the set of samples comprises a first subset of samples having an associated first strike force value and a second subset of samples having an associated second strike force value different from the first strike force value; and
transferring one of the first and second subsets of samples to a first memory from a second memory before transferring another of the first and second subsets of samples based on a strike force value associated with the priority-instruction.
16. The method of claim 15 , further comprising receiving a trigger signal and playing the first subset of samples in response to the trigger signal before the second subset of samples is transferred.
17. The method of claim 15 , wherein the priority-instruction specifies that the first subset of samples should be transferred before the second subset of samples.
18. The method of claim 15 , wherein the priority-instruction specifies transferring a subset of samples that are expected to be triggered before another subset of samples.
19. The method of claim 15 , wherein, based on the set of samples, the first subset of samples is expected to be triggered before the second subset of samples.
20. The method of claim 15 , wherein the set of samples further comprises a third subset of samples and wherein the method further comprises determining whether the third subset of samples was previously transferred.
