My drum kit sensitivity is off - I'm dropping notes or hitting notes twice in a row unintentionally. What's going on?


PAD SENSITIVITY & DROPPED DRUM PAD HITS


We have identified and adjusted a number of cross-talk and sensitivity issues on the Rock Band 4 drum set.  If you have a controller that exhibits this problem, we have a firmware update that’s currently available to address the issue.  The feedback we have gotten is that the firmware update successfully resolves the dropped hit issues (commonly found in fast roll sections, for example).  Testing at Harmonix and at Mad Catz has concluded the same.  Here is the link to the firmware updates for anyone who has not found their way there:

It is strongly recommended that you re-calibrate your game anytime you update your firmware.

 

KICK PEDAL SENSITIVITY


The Rock Band 4 kick pedal was modeled directly after the Rock Band 3 pedal and has a slightly higher actuation point (height at which the switch is engaged to register a hit) than the pedals from legacy Rock Band games like Rock Band 2 and The Beatles: Rock Band.    The end result is that some players that play “heel up” as opposed to “heel down” on the pedal prefer the action from the earlier pedals.   Most players that play “heel down” will find the Rock Band 4 pedals more responsive because they hit the actuation point faster. “Heel up” players find the legacy pedals more responsive because they don’t need to depress the pedal as much to register the next hit.   For players that prefer the legacy pedals, they absolutely will be compatible with the new Rock Band 4 drum kit – feel free to plug those in and use them! This does not require an adapter; you can plug your legacy Rock Band pedal directly into your Rock Band 4 drum kit. For players that are looking for more sensitivity when playing “heel up” and do not have access to a legacy Rock Band pedal, there are folks who have made some simple modifications to the pedal using rubber stoppers with adhesive or other materials that simply shorten the travel distance of the pedal to reduce the distance from the actuation point to the fully pressed state, resulting in slightly faster response time for those players. 

 

KICK PEDAL DOUBLE HITS


We are aware of the issue players are seeing where double hits (two kick drum notes in very quick succession) or other extremely fast kick drum passages are not fully registering, i.e. players are experiencing dropped notes.   We have been able to reproduce this issue on expert difficulty in several songs.   We are also aware that it is pedal agnostic – meaning folks using legacy Rock Band pedals with the shorter actuation point, or even higher end pro pedals can still experience this issue to some degree. The drum set has a calibration number which the game uses to compensate for how long it takes the drums to register a hit and send that data to the console.   The drum pads use a complex algorithm to help filter out cross-talk and other vibration so that the drums do not register false hits.  This process takes a few milliseconds (~20-30ms specifically).   The drum pedal uses a simpler magnetic switch to register a hit so it has a much shorter data path to the console.  The firmware inside the drum set helps compensate for the difference between those timings so that the calibration value you set for your drum set feels right for pad hits and pedal hits.    Based on the feedback we have been seeing from pro & expert drummers about latency and double hits, we have reworked the logic in how we resolve those two timing differences.    The result is a new version of the firmware, which is available now!
